Your string-to-codepoints example only works for ASCII upper/lower case
letters. It fails to recognize composed and decomposed diacritical characters
such as a combined uppercase A with a grave U+00C1, with an accute U+00C1,
with a circumflex U+00C2, etc. Yes you could detect these too with additional
logic, but matches() with a character class of \p{Ll}, \p{Lu}, \p{Lt} handles
all the messy details of Unicode.
