noncharacter-regex

Regular expression for matching or stripping non-characters from a string.

Install with npm

npm i noncharacter-regex --save

Usage

var regex = require('noncharacter-regex');
regex.test('abc\uFFFExyz');
//=> 'true'

// strip non-characters
'abc\uFFFExyz'.replace(regex, '');

What's this all about?

non-characters are useful, for example, when you're doing string transformations and you need to use temporary placeholders to avoid unintentional mutations. In those cases, this regex would be used before do your transformations to ensure that any existing non-characters are removed before you do your replacements.

Does that happen!?

It's unlikely, but from time to time the U+FFFE non-character may show up in strings since it has the reverse binary sequence of byte-order marks.
