FAQ
How is camelCase boundary detected?
Case transitions, non-alphanumeric separators, and consecutive uppercase followed by lowercase. e.g. HTTPServer → http_server.
Are Chinese characters affected?
Case conversion ignores Chinese. Full-width ↔ half-width does convert Chinese punctuation and full-width digits.
What exactly is full-width vs half-width?
Width refers to display width: letters, digits, spaces and common punctuation each have full-width Unicode equivalents (e.g. ＡＢＣ ↔ ABC).
Can I customize the separator?
The 15+ built-in formats cover most needs. For special separators, convert to kebab-case and use find-and-replace.
