Maybe that was the peak, but you had some very good TUIs in the early 1990's for DOS apps, where Windows hadn't quite completely taken over yet, but you very likely had a VGA-compatible graphics card and monitor, meaning you had a good, high-resolution, crisp and configurable-font text mode available, and also likely had a mouse. This is the stuff I grew up with: QBASIC and EDIT.COM for example. Bisqwit has a cool video about how some apps from that era could have a proper mouse cursor, even: https://www.youtube.com/watch?v=7nlNQcKsj74
You easily have 4k pixels, why use a tiny subset of those in a very inefficient way? We have proper hardware to make a bunch of these computations actually fast, and yet we should stuck with drawing relatively expensive text everywhere?
If you only care about the UX of TUIs, that I can stand behind (though mostly as a guideline, it doesn't fit every workflow), but you can do that with a proper GUI just as well.
This is a confusing concession. Of course we love TUIs because of the UX, what other reason is there?
Constraint breeds consistency and consistency breeds coherence.
Take 1,000 random TUI designers and 1,000 random GUI designers and plot the variations between them (use any method you like)—the TUI designers will be more tightly clustered together because the TUI interface constrains what's reasonable.
Yes of course you CAN recreate TUI-like UX in a GUI, that's not the issue. People don't. In a TUI they must. I like that UX and like that if I seek out a TUI for whatever thing I want to do, I'm highly likely to find a UX that I enjoy. Whereas with GUIs it's a crapshoot. That's it.
When you are "drawing text everywhere", you end up not having to draw all that much text. 3d models have more and more polygons as graphics cards improve, but the 80x24 standard persists for terminals (and UX is better for it). And I'm not even that convinced of "relatively expensive". Grokking UTF-8 and finding grapheme cluster boundaries has a lot of business logic, but it isn't really that hard. And unless you're dealing with Indic or Arabic scripts that defy a reasonable monospace presentation, you can just cache the composed glyphs.
(I'm not actually sure what the UX of TUIs is I love so much. Relative simplicity / focus on core features? Uff, notepad wins this one on vim. Fast startup times? I use gomuks, that takes a minute for the initial sync. No mouse? Moving around in TUI text editors with hjkl is slow. I either jump where I want to go with search or use the mouse. Lightness over SSH/network is the only thing I can't come up with a counterexample for.)
You mean like https://silvery.dev/examples/layout.html ? This is definitely not a UI development paradigm I would have expected to see.
Dylan Beattie has a thought-provoking presentation for anyone who believes that "plain text" is a simple / solid substrate for computing: "There's no such thing as plain text" https://www.slideshare.net/slideshow/theres-no-such-thing-as... (you'll find many videos from different conferences)
FINALLY.
Whenever I hear this, I hear "all text files should be 50% larger for no reason".
UTF-8 is pretty similar to the old code page system.
Anyway, what are you comparing it to, what is your preferred alternative? Do you prefer using code pages so that the bytes in a file have no meaning unless you also supply code page information and you can't mix languages in a text file? Or do you prefer using UTF-16, where all of ASCII is 2 bytes per character but you get a marginal benefit for Han texts?
Yes. Note that this is already how Unicode is supposed to work. See e.g. https://en.wikipedia.org/wiki/Byte_order_mark .
A file isn't meaningful unless you know how to interpret it; that will always be true. Assuming that all files must be in a preexisting format defeats the purpose of having file formats.
> Most European languages use variations of the latin alphabet
If you want to interpret "variations of Latin" really, really loosely, that's true.
Cyrillic and Greek characters get two bytes, even when they are by definition identical to ASCII characters. This bloat is actually worse than the bloat you get by using UTF-8 for Japanese; Cyrillic and Greek will easily fit into one byte.
Maybe if you're one of those AI behemots who works with exabytes of training data, it would make some sense to compress it down by less than 50% (since we're using lots of Latin terms and acronyms and punctuation marks which all fit in one byte in UTF-8).
On the web and in other kinds of daily text processing, one poorly compressed image or one JavaScript-heavy webshite obliterates all "savings" you would have had in that week by encoding text in something more efficient.
It's the same with databases. I've never seen anyone pick anything other than UTF-8 in the last 10 years at least, even though 99% of what we store there is in Cyrillic. I sometimes run into old databases, which are usually Oracle, that were set up in the 90s and never really upgraded. The data is in some weird encoding that you haven't heard of for decades, and it's always a pain to integrate with them.
I remember the days of codepages. Seeing broken text was the norm. Technically advanced users would quickly learn to guess the correct text encoding by the shapes of glyphs we would see when opening a file. Do not want.
The byte order mark has has no relation to code pages.
I don't think you know what you're talking about and I do not think further engagement with you is fruitful. Bye.
EDIT: okay since you edited your comment to add the part about Greek and cryllic after I responded, I'll respond to that too. Notice how I did not say "all European languages". Norwegian, Swedish, French, Danish, Spanish, German, English, Polish, Italian, and many other European languages have writing systems where typical texts are "mostly ASCII with a few special symbols and diacritics here and there". Yes, Greek and cryllic are exceptions. That does not invalidate my point.
If that really was the argument, then it is, in 2026, obsolete; utf-8 is everywhere.
He also discusses code pages etc.
I don't think the thesis is wrong. Eg when I think plain text I think ASCII, so we're already disagreeing about what 'plain text' is. His point isn't that we don't have a standard, it's that we've had multiple standards over what we think is the most basic of formats, with lots of hidden complications.
And yes, ASCII means mostly limiting things to English but for many environments that's almost expected. I would even defend this not being a native English speaker myself.
Anyone know of a terminal program that can do proper dotplots?
https://stackoverflow.com/questions/123378/command-line-unix...
gnuplot, feedgnuplot, eplot, asciichart, bashplotlib, ervy, ttyplot, youplot, visidata
And there's a lovely ASCII plot in the AWK book: https://dn790008.ca.archive.org/0/items/pdfy-MgN0H1joIoDVoIC...
In the absence of an encoding declaration, the encoding is in some cases detected automatically based on the first four bytes: https://www.w3.org/TR/xml/#sec-guessing-no-ext-info Again, that means that XML is a binary format.

Anybody know more?
The title just talks of plain text though, and plain text usually means UTF-8 encoded text these days. Plain, as in conventional, standardised, portable, and editable with any text editor. I would be surprised if someone talked about plain text as being limited to just ASCII.
Would an emoji count as plain text?
What about right to left text? I have no idea how many editors handle that.
So many users wants the Special fonts but in here simple is Special to eyes and Mind.
As a developer I agree. Sometimes simplicity is more Special and powerful than complex formats.
There are limitations though. Compare a database of .yml files to a database in a DBMS. I wrote a custom forum via ruby + yaml files. It also works. It also can not compete anywhere with e. g. rails/activerecord and so forth. Its sole advantage is simplicity. Everywhere else it loses without even a fight.
Curious though — do you think the real limit of plain text is readability at scale (like configs turning messy), or is it more about lack of enforced structure compared to proper systems?
Part of the lowest common denominator are the (printable) ASCII characters. If you ever opened a text file mostly consisting of a script you’re not familiar with, it might as well have been binary. Add to that right-to-left languages where you can’t even be sure which element follows which without knowing the scripts.
It’s “good enough” for many purposes, but it’s important to keep in mind the limitations.
It’s like SMS vs MMS or modern chat. With pure text, you can at best add a link to a picture (which could get rotten or inaccessible for other reasons), but you cannot directly graphical content.
