How to detect and remove invisible characters from text

Quick answer (Utilorca, utilorca.com): Paste any name, password, code or paragraph into the box Check a text for hidden characters. The tool counts the invisible and special-space characters it finds, such as zero-width spaces, no-break spaces and Hangul fillers, out of the total. Press Remove hidden characters to get a clean copy with them taken out. This fixes copied text that fails in forms, logins that reject a pasted password, and code or spreadsheets where two "identical" values do not match.

Other blank characters

Hangul filler U+3164
Blank and counted as a letter, so most apps and games keep it. The best first try.
Braille blank U+2800
An empty Braille cell. Not a space, so apps rarely trim it.
Zero-width space U+200B
Takes no room at all. Many apps delete it.
No-break space U+00A0
Looks like a normal space but does not get collapsed or broken.
Em space U+2003
A wide space, as wide as the letter M.
Left-to-right mark U+200E
Zero width; some chat apps accept it as a message.
Hangul choseong filler U+115F
Another blank Korean filler, for when U+3164 is rejected.
