I’ve always wondered why there weren’t more non-english charactered programming languages but I can only assume it was just inertia

This seems like a reasonably good security measure too

I think another part of it is culture. Outside of Western tech circles there's far less a culture (it feels) to invent new languages. To my knowledge Ruby's Matz is the only notable exception, and he's highly unusual as a Japanese. Then, using non-ascii-friendly character set is an even greater challenge.

Non-ascii encodings are harder to program in due to the need to switch in and out of input methods.

That said, some languages like Arabic and Japanese (and possibly Korean and Hindi) lend naturally to VSO token ordering, which maps directly to LISP syntax, so it's unfortunate that there isn't a lot of interest in this. It would be lots of fun. Maybe agents will make this possible!

Here are some interesting examples.

    - https://github.com/nasser/--- (Arabic)
    - https://honoka.nukenin.jp/Introduction/Loop.html (Japanese)
    - https://github.com/wenyan-lang/wenyan (Chinese, which is SVO like English)

Using english for your programming language gives you the widest audience.
