I love seeing nonsense like that. How that work graphically though? Just keep adding to a same QR code that keeps getting denser as more text is added? I guess it doesn't have to practical though :)
The downvotes aren't saying the comment is wrong (though it might be), they are saying “if it is that easy, you ask Claude”. The parent comment seemed to be specifically asking if a person would work on it, not specifying what tools might be used in that work.
It seems like it doesn't do this for Code 128 (possibly because it is variable-width?). It definitely works with EAN13 though - I tried it locally using only the TTF file.
Do not do this unless you do not have any other choice. Preferrably use whatever native barcode support of the printer involved, if it does not have that, just generate the barcode as vector image or bitmap with a resolution that is a integer fraction of the printers resolution. Generating correct Code128 as a SVG is about the same amount of work as generating the correct input for some sort of barcode font (the hard part is determining the switches between character sets, not generating bars from bytes).
Shameless plug for my web-based Zint frontend: https://barcode.new
(in-browser WASM)
I wrote it specifically because most online barcode generators don’t support vector output or suck in some other way: ads, signup necessary, code payload exposed to server-side processing etc.
This would be more interesting if you wouldn’t need to calculate checksums yourself, and could just write the barcode value. Good luck doing that with something like Reed-Solomon (QR, Data Matrix, etc.) or the shenanigans they’re doing with GS1 DataBar.

Marelle is a free cursive police force for teaching writing in elementary school.
Introduction
This project is supported by the Digital Directorate for Education of the Ministry of National Education, and developed in the Forge of Digital Educational Commons.
The Marelle police is designed specifically for teaching cursive writing in elementary school, it was developed by a team of teachers and designers specialized in writing systems.
Teaching Cursive Writing
Structure and sequence of letters, rhythm and proportion, contextual variants: the Marelle font was thought around specific criteria to offer a quality model to teachers and students.
Particular attention has been paid to the trace of numbers, capital letters and punctuation.
A complete professional tool
The Marelle police offers 3 types of variants:
uppercase sticks or cursive
with or without lineage Seyes
height of ascendants and descendants
These variants can be combined to best meet the needs of teachers and students." etc
Nice! That looks pretty similar to the one in "Cuadernos Rubio", a system that was super popular from the 60s to the 90s in Spain (that still exists) for learning handwriting in primary school.
Even with plain ASCII we sometime struggle with the various scanners, as they emulate keyboards. So for instance using : in the barcode as a separator of values becomes wonky if the OS has a different input language than expected.
Code 128 supports some ISO-8859-1 indeed, but it requires switching between encodings (there are 3 of them), and couldn't work with 128B (I guess the one used by the font, as it supports ASCII). See the table on Wikipedia: https://en.wikipedia.org/wiki/Code_128
actually it seems they support 128A 128B and 128C with the correct encoder.
To use these fonts you have to use an encoder like the one below. It is an optimizing encoder, that means, it produces the shortest barcode that can encode the input. For this the encoder, if necessary or shorter, switches between the three available Code Sets (list from Wikipedia):
The fact that this is standard practice does not mean that it is not perverse. It kind of works sanely for plain Code39 (and even then you will see effects of doing that in weird places, like VAG stamping human readable VIN on a chassis, including the Code39 start/stop symbols), once you start using barcode fonts for Code128-derived symbologies (ie. UPC/EAN) the whole thing becomes a pointless exercise.
I wrote it specifically because most online barcode generators don’t support vector output or suck in some other way: ads, signup necessary, code payload exposed to server-side processing etc.
Another cool font, but less original, I stumbled upon recently is Marelle https://marelle.forge.apps.education.fr/ for cursive.
This website is in French so I was unable tounderstand the text
and the website is very resistant to automatic translation by Google Translate

What gives?

It looks like Code 128 could potentially handle some ISO-8859-1 accented latin characters, but I'm not sure how to test it.
