Required Methods

fn remove_all_invisible_characters(self) -> Cow<'a, str>

Removes all invisible or non-printable characters from a given string.

This function filters out a comprehensive set of Unicode characters that are typically invisible or used for control or formatting purposes. This includes:

• ASCII control characters (U+0000 to U+001F and U+007F), exclude \t and \n
• Zero-width characters and format controls:
  • U+200B (Zero Width Space)
  • U+200C (Zero Width Non-Joiner)
  • U+200D (Zero Width Joiner)
  • U+200E to U+200F (Directional marks)
  • U+202A to U+202E (Directional formatting)
  • U+2060 to U+2064 (Word Joiner and Invisible Math Symbols)
  • U+2066 to U+2069 (Bidi Isolates)
  • U+FEFF (Byte Order Mark / Zero Width No-Break Space)

These characters can interfere with text rendering, parsing, and display, and are often used in text-based attacks (e.g., for spoofing).
