Questions about the Text Case Converter
Does it handle acronyms correctly in camelCase?
Yes — 'XMLHttpRequest' stays as 'XMLHttpRequest' when converted to PascalCase, not 'XmlHttpRequest'. The converter recognizes consecutive uppercase letters as acronyms and preserves them.
What about sentence-case rules with proper nouns?
Sentence case lowercases everything except the first letter of each sentence. We don't auto-detect proper nouns — they'll get lowercased too. Fix manually after if it matters.
