Worked example
XMLHttpRequest → snake_case
xml_http_request
Latin case transitions and separators define word boundaries. Basic upper/lower modes retain punctuation, while naming modes rebuild the separators.
How are Korean words and acronyms handled?
Korean words are retained. Latin casing uses en-US rules rather than every language’s casing conventions. Review names manually when preserving an acronym’s exact capitalization matters.
