Javascript regExp cyrillic pattern

I know this is a stupid question, but I spent two days with no results. What should be the regExp pattern, allowing my user to enter only Cyrillic characters and spaces? Thanks in advance!

You cannot do this in Javascript because Javascript does not provide even the simplest Unicode level 1 support in your regular expressions. You will need to switch languages ​​to do this correctly.

You cannot use the listed block ranges for this. This confuses blocks and scripts that are deeply corrupted. There are 150 code points that have a property \p{Script=Cyrillic}but that do not have a property \p{Block=Cyrillic}. They are in different blocks. Watch:

$ unichars '\p{Script=Cyrillic}' '\P{Block=Cyrillic}' | wc -l
150

In addition, the Cyrillic block has a pair of non-cyrillic code points.

The best thing you could do is list all 404 Cyrillic code points as a class of characters that can turn out to be prohibitive.

$ unichars '\p{Script=Cyrillic}'  | wc -l
404

You can use unichars scripts to list everything if you really want to. You may also want to grab the uniprops script while you are there.
