Paste text containing accented letters, and the tool strips the accents and diacritics (café → cafe) and transliterates ligatures to plain ASCII.
Text is Unicode-normalized (NFD) to separate base letters from their diacritical marks, then all combining marks are stripped, leaving plain ASCII letters.
Ligatures like æ, œ, ß, ø, ł and đ don't decompose into a base letter plus accent, so they're transliterated separately (æ→ae, ß→ss, ø→o) when the option is enabled.
Yes — removing accents produces clean ASCII text that's safe for URLs, filenames, and systems that don't handle Unicode well.
