Probably what I’m about to write will be known to someone, but just recently they have come across this for the first time.

Works in cp1251 encodings and in UTF, tested on versions php 4.4.7, 5.2.9, 5.2.10–2ubuntu6.4

All code works for me

Benefit

To be honest, there were no immediately ideas for the practical application of Cyrillic in the code. Well, except to write some funny constructions and lay out in code_wtf. Let's discuss the prospects for using this.

Harm

Actually, it all started with harm, when the Russian sneaked into the variable name with . If you do not use syntax highlighting and spelling checker in the code “on the fly”, then you can spend a lot of time looking for errors.
Also, it will not be very pleasant for non-Russian coders who will have to accompany the project. Although, the fact that they sometimes leave us ... Well, okay, the post is not about that.

findings

Maybe "Give us our code!", Eh? or well him?
Be alert, in a word.
