FAQ

Frequently asked questions

Which characters are reported?

Control characters, including tabs and line breaks, characters from U+007F to U+00A0, and Unicode format characters such as zero-width spaces and direction marks.

Why do hidden characters matter?

They make identical-looking strings differ, break search and parsing, and can be used to disguise links or code.
