how to add russian characters in regex?

[galaxyandrew]

I have a command / t set board (text) and if this text is in Russian it will write that the wrong characters tell me what to write in the regex:
name_filter_regex: '[\\ /]'
name_check_regex: ^ [\ p {L} a-zA-Z0-9 ._ \ [] -] * $
string_check_regex: ^ [a-zA-Z0-9 \ s ._ \ [] \ # ? ! \ @ \ $ % \ ^ \ & \ * \ - , \ * \ () \ {\ }] * $
name_remove_regex: '[^]'

\p{L} needs to be in the string_check_regex.
