Useful things to know
Case rules are language-neutral and use Unicode letters. Upper/lower/title/sentence styles preserve spacing; identifier styles split camel/Pascal/acronym boundaries, remove separators and join words. Some Unicode case mappings change length. Title and sentence rules are mechanical, not editorial grammar or proper-name recognition. Identifier output is not checked against a programming language’s naming rules. Counts use Unicode code points rather than rendered grapheme clusters. Text remains in temporary page memory.
