Strictly speaking, to match a general character, you need to search for its decomposition. If this character also has a case "equivalent" (as per current-case-table), you can also search for the decomposition of this equivalent. --001a113fb2a45bcd750526151e1f Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

Won't match cross-case.

Yes. Visual appearance is irrelevant.

Strictly speaking, to match a general character, you need to= search for its decomposition. If this character also has a case "equi= valent" (as per current-case-table), you can also search for the decom= position of this equivalent.
