tell whether a character is a combining diacritic mark

Question

if you're looping though the chars a unicode string in python (2.x), say:

ak.sɛp.tɑ̃

How can you tell whether the current char is a combining diacritic mark?

For instance, the last char in the above string is actually a combining mark:

ak.sɛp.tɑ̃ --> ̃

Use the unicodedata module:

import unicodedata
if unicodedata.combining(u'a'):
    print "is combining character"
else:
    print "is not combining"

This fails for `U+20DD COMBINING ENCLOSING CIRCLE`, or `⃝`. – user202729 May 11 '23 at 14:41
