What’s the difference between Title and Sentence case?
Title Case: Every Word Starts Big. Sentence case: only the first letter of each sentence — generally more readable for body text.
Does it handle accented characters?
Yes — conversions use Unicode case mappings, so accented letters convert correctly.
Can I undo a conversion?
Inverting case twice returns the original for alternating and inverse case. For Title/Sentence conversions, keep the original text until you’re happy with the result.
