How can I match any Unicode letter (no symbol, number or any other kind of character), i.e. letter from alphabet of any language, in the Angular pattern
directive? Previously I've used AngularJS and I've just installed XRegExp plugin for it, but since Angular 5 is using TypeScript, I was trying to find a way to do this without using the mentioned plugin. But I can't seem to find any other way...
EDIT: I'm looking for a straightforward way, without using plugins and without insanely long list of unicode charater ranges.
