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
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.
Anyone know of a terminal program that can do proper dotplots?

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.
