Why is that rude and disrespectful? I'm certainly respecting developers who want to use their scripts for identifiers, or else I would not have suggested that they could do so. However, from the experience with my own language, and the three or so foreign languages I know, I can tell you that people would normally don't mix identifiers of different scripts. > Sure, that example was made up, but there are words which have been > stolen from various languages by english, and you are discounting the > case of single-letter temporary variables.

They get an error, and then will need to find the cause of the problem. Sometimes, this will be easy, and sometimes, it will not. > Indeed, they are similar, but_ different_ in my font as well.

This string: "EΕ" is the LATIN CAPITAL LETTER E, followed by the GREEK CAPITAL LETTER EPSILON. In the font my email composer uses, the E is slightly larger than the Epsilon - so there /is/ a visual difference. But even if there isn't: if this was a frequent problem, the name error could include an alternative representation (say, with Unicode ordinals for non-ASCII characters) which would give an easy visual clue. I still doubt that this is a frequent problem, and I don't see any better grounds for claiming that it is than for claiming that it is not.
