1218 Use "\%C" to skip any composing characters. For example, the pattern "a" does
1219 not match in "càt" (where the a has the composing character 0x0300), but
1220 "a\%C" does. Note that this does not match "cát" (where the á is character
1221 0xe1, it does not have a compositing character). It does match "cat" (where
1222 the a is just an a).
