Is there a way to get cyrillic suffixes working for signal numbers?

[river patrol]

for example 3k works if you type it in the signal input, but 3к does not work. The UI however is able to display numbers like this

this above is from typing 2k and not 2к

You will have to ask about this on the forums, probably as a feature request.

The feature is pretty new, so this may simply not have been considered
