deburr

Replaces accented Latin letters with their unaccented equivalents, so 'déjà vu' becomes 'deja vu'.

Letters that have no single-letter equivalent are spelled out: Æ becomes Ae, ß becomes ss, Þ becomes Th, Œ becomes Oe and IJ becomes IJ.

Combining marks are removed as well, so text written in a decomposed form (e followed by U+0301 instead of é) is handled too.

The mapping covers the Latin-1 Supplement and Latin Extended-A blocks, plus combining marks. That is what can be expressed as a plain table in all three languages, since Dart offers no Unicode normalization. Anything outside those blocks is returned as it is — Vietnamese Tiếng Việt and Hangul, CJK or Cyrillic text are left untouched.
