Non-ASCII Script Support

Not everyone on Earth uses an ascii-compatible language, though.

Any idea on how it does on other languages? In particular, non-Latin languages like Arabic, Persian, Urdu, Hindi, etc.?

Kind of shocked to be reading this... have you ever made software for non-English speaking users? ASCII is not enough.

I think it might have something to do with the ~7 billion people whose native language isn’t expressible in ascii. Just maybe?

Would it be normal to not translate these into languages that share the Latin alphabet at least?

You're basically throwing people with "inconvenient" character sets (i.e. everything that doesn't use something strongly resembling Latin characters) under the bus. Sure, you might be able to support Spanish, French, and German, but you're basically disregarding Japanese, Chinese, and Hindi when doing so (and possibly even ASCII, since you'd trade some symbols for accents).

They should have thought of that before they put non-ASCII characters in their language.

Do "most non-English" languages have normalization issues? At least CJK users do not.

Perhaps it looks like it works "almost perfectly" because you're only using English (and similar western languages)? the problems that arise in Asian text are numerous -- and they do frequently hit end users.

feel the same. there's a lot of people out there who never get a chance to learn any english. to write your own code based on ascii / latin char set might be ok, but to interpret other's code etc. would be very difficult. so for example in a school, having only code examples with ascii could be a significant barrier to teach ,when all other subjects presented are in the local language / character set.
