The unicodedata module has all the information you need for searching
Unicode character names. While it doesn't provide regex or globs, it's
all in-memory, so it's not bad for just iterating over the characters
and finding what you need.
But, 'CAP' appears in 'CAPITAL', which gives more than 1800 matches:
>>> for c in range(32, 0x110000):
... try:
... name = unicodedata.name(chr(c))
... except ValueError:
... continue
... if 'CAP' in name:
... print(c, name)
...
65 LATIN CAPITAL LETTER A
66 LATIN CAPITAL LETTER B
..
.. many other lines, mostly with CAPITAL in them ..
..
917593 TAG LATIN CAPITAL LETTER Y
917594 TAG LATIN CAPITAL LETTER Z
>>>
These were the character names without "CAPITAL":
