Character escapes for XML ids are incorrect for some characters

The buggy code is here:

omw-data/scripts/util.py

Lines 67 to 68 in 0a94425

	elif codepoint in codepoint2name:
	chars.append(codepoint2name[codepoint])

The custom mapping already has the dash escapes (e.g., -apos-), but those that are looked up from Python's html.entities.codepoint2name do not get the dashes. The fix is essentially:

         elif codepoint in codepoint2name:
-            chars.append({codepoint2name[codepoint]})
+            chars.append(f"-{codepoint2name[codepoint]}-")

A second thing is that underscores are not escaped and spaces are replaced with underscores, resulting in a conflation of the two characters. The fix here is to add it to the escape patterns: -lowbar-
