I am looking for a way to detect non-ascii characters in a string and return them as failure:
The current method successfully detects one non-ascii character:
/[\x20-\x7E\s]/.test('☃')
However, it fails when the non-ascii character is part of a string:
/[\x20-\x7E\s]/.test('sus☃')
To match any character outside the specified range, you can use a negated character class:
!/[^\x20-\x7E\s]/.test('sus☃')
Alternatively, you can utilize anchors and a quantifier:
/^[\x20-\x7E\s]+$/.test('sus☃')
In this case, + is being used (which requires one character). You could also opt for * instead (matching zero or more characters).
