unicodedata.name

[Szabolcs Nagy]

the unicodedata manual sais:
"
name( unichr[, default])
Returns the name assigned to the Unicode character unichr as a
string. If no name is defined, default is returned, or, if not given,
ValueError is raised.
"
what is the difference between "no name defined" and "not given"?
eg. '\n' why gives a ValueError?

>>> unicodedata.name(u'\n')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: no such name

"no name is defined" refers to the unicode database, "not given"
refers to the default argument. if you don't specify a default, and
the character don't have a known name, you get a ValueError.

the Unicode standard doesn't specify names for control characters.
