Text processing & transformation mechanics
Sanitizes irregular whitespace and harmonizes mixed CJK/Latin typography in accordance with W3C Requirements for Chinese Text Layout and Unicode Standard Annex #15 (Unicode Normalization Forms NFC, NFD, NFKC, NFKD). Implements the Pangu spacing rule by automatically inserting half-width spaces between CJK characters and Latin alphabets, numbers, or symbols. Detects and scrubs invisible non-printing Unicode characters (Zero-Width Space U+200B, Zero-Width Non-Joiner U+200C, Zero-Width Joiner U+200D, Left-to-Right Mark U+200E, Byte Order Mark U+FEFF, and soft hyphens U+00AD).

Frequently asked questions
Which characters does Invisible Characters Cleaner remove?+
It removes only U+200B, U+200C, U+200D, and U+FEFF from the supplied text. All other characters and whitespace remain unchanged.
Does it detect every unusual Unicode character?+
No. Other format controls, bidi markers, variation selectors, nonbreaking spaces, soft hyphen, and confusable characters remain because they are outside this four-code-point rule.
Can cleaned text restore removed invisible data?+
No. Removal is destructive in the resulting text. Keep an original copy when hidden markers may carry intentional content or evidence.
Can I try a concrete input?+
Paste `a`, then U+200B, then `b`, then U+FEFF, then `c`. Run locally returns the visible text `abc`.
