Answer 1

You could just remove all non-letters, non-numbers and non-dash with [^a-z0-9\\- ... ЛЁ ... ] :

var foo = 'jbgsbg5%E-th-t65?tw45@%^&*j-y&u-САМОЛЁТ~   ~2><%27;[]~!6456';

foo
    .replace(/\s+/g, "") // remove whitespaces
        .replace(/[^a-zA-Z0-9\- ... ЛЁ ... ]/ig, "") // remove non-letters, non-numbers and non-dash characters
            .replace(/\-+/g, '-'); // replace multiple `-` character with single `-`

Where ... ЛЁ ... is for all of your Roman letters.

Answer 2

You can try with this regular expression in your javascript :

[\u00BF-\u1FFF\u2C00-\uD7FF\w\-]+
