You mean a code point, then (that's basically what gunichar is). I think
the reason Unicode people are so pedantic about "code point" is because
a code point may or may not be what you actually mean when you say
"character", whereas it's rare that I see "code point" used with a
meaning other than its Unicode one.

More precisely, a Unicode code point is an abstract entity indexed by a
number, such as U+0041 LATIN CAPITAL LETTER A or U+262D HAMMER AND
SICKLE, which can only be concretely represented as some particular byte
sequence by passing it through an encoding like UCS-4, UTF-8 or
ISO-8859-1. Some encodings are more obvious than others, and in
particular non-Unicode encodings like ISO-8859-1 cannot represent every
Unicode code point.
