What is Invisible Character Detection

Hidden formatting characters like Zero Width Spaces (ZWSP), Byte Order Marks (BOM), and RTL Directional Overrides are frequently embedded in copied text from websites, PDFs, or chat applications. While invisible to human eyes, they can cause bugs in code compilers, fail database validation filters, or disrupt search indexing.

What This Tool Catches:

  • Zero-Width Spaces & Joiners: ZWSP (`U+200B`), ZWNJ (`U+200C`), and ZWJ (`U+200D`).
  • Layout & Byte Markers: Byte Order Mark (`U+FEFF`), Soft Hyphens (`U+00AD`), and Word Joiners (`U+2060`).
  • Directional Formatting Marks: Left-to-Right / Right-to-Left overrides and embeds (`U+200E`, `U+200F`, `U+202A`–`U+202E`).

Complete Privacy Guarantee
