fn universal_keysym(c: char) -> Option<u32>Expand description
Universal keysym for a character: Latin-1 keysyms are their codepoint and
everything above rides the Unicode plane — the two encodings every compositor
and toolkit translate algorithmically. Editing controls map to their keys;
other controls have no keysym. Fixed grammar only: which keysym spells a
char in any richer sense is selkies’ policy, delivered via type_keysyms_to.
