Return if string has valid characters

Question

I want to make function, that works like Windows' rename function .

When you type text and regex is a-zA-Z0-9 then you can type only "alphanumeric" characters. But characters like -, _ or + would be accepted too. Also non-english characters like č š ý ž í á should be accepted too.

you can use [^\/:*?"<>|], check this regexr.com > CheatSheet, very useful — guramidev

if I understand right, this regex will take all characters except of these in [...]? — Patrik Krehák

If you just want to not allow those characters in the bubble then:

function filenameOk(name){
    return !/[\\/:*?<>|]/.test(name);
}

// filenameOk('čšýžíá') --> true
