UniQueryUconvObject queries the attributes and characteristics of the given conversion object. The attributes are used to modify the default conversion.

The substitution character attributes specify to the conversion object how to perform in cases that there is no identical character for a given code element. UniQueryUconvObject may be used to query the substitution characters used by the conversion.

Some of these are static and bound to the conversion table; others are settable through UniSetUconvObject

The following parameters can be NULL to indicate that this data should not be returned:

attr
first
other
udcrange

See the uconv_attribute_t to see the conversion object attributes; the structure indicates which fields can be queried and which can be set through UniSetUconvObject.
