Exact steps for others to reproduce the error

Open attached blend file cyr_case.blend
Text Editor → Run Script
In operator search find two operators:
- Search Popup: Latin

For English speakers here is two Cyrillic characters which you can copy and paste in search popup for testing:
Capital case: "К"
Lower case: "к"

Here is the reult you should get:

Thanks for the report, but this is more a known limitation than a bug - issue is, standard C library embeds helpers to handle case of latin alphabet (limited to non-accented letters though), i.e. basic A-Z letters. To handle cases in all other scripts, one need a dedicated Unicode library, which is much more heavy process.

Currently, in Blender we follow that rule about unicode text: we support it provided it’s not too much work. :/

Maybe related: in spanish you need to be rigorous when searching for accented words, for instance you need to type 'menú' as 'menu' won't do it. But in browsers and other programs you just search without accents and it works fine. Just curious if this could be improved, not a big problem, thanks.

These news strike right into my Cyrillic heart.

@lowercase yes, as I said even latin accented letters are not working, only 'pure' ASCII a-z ones are handled.

@MikhailRachinskiy Yeah… and think about people using complex scripts from India and other far east countries - they do not even have proper rendering of their languages in blender currently (because those need a complex layout engine).

Note that I just discovered and tried towlower() C func, but result is not really enthusiasming either, depends too much on defined locale to be usable for us.

Language-specific comparison and sorting would be a good job for ICU - International Components for Unicode

Converting to lower case at least can work for alphabetical-based languages, i think.
IMO it is better to make something work than leave issue for all.

Also I am sure, that ppl from different countries will be glad to tell about language spicific and help to fix it.
Looks like it big issue, if it is right inside C.
