How it works & limits

Splits whitespace, underscores, hyphens and ASCII case boundaries, including acronym boundaries. Other punctuation is removed; Unicode letters, digits and attached marks remain.

Example: HTTP server name becomes httpServerName. Words are case-folded before joining; this is not language-aware word segmentation or a programming-language identifier validator.
