XmCvtXmStringToCT converts a compound string to a (char*) string in compound text format. The
application must call XtAppInitialize before calling this function. The converter uses the font list tag
associated with a given compound string segment to select a compound text format for that segment. A
registry defines a mapping between font list tags and compound text encoding formats. The converter uses
the following algorithm for each compound string segment:
1. If the compound string segment tag is mapped to XmFONTLIST_DEFAULT_TAG in the registry, the
converter passes the text of the compound string segment to XmbTextListToTextProperty with an
encoding style of XCompoundTextStyle and uses the resulting compound text for that segment.
2. If the compound string segment tag is mapped to an MIT registered charset in the registry, the
converter creates the compound text for that segment using the charset (from the registry) and the
text of the compound string segment as defined in the X Consortium Standard CompoundTextEncoding.
3. If the compound string segment tag is mapped to a charset in the registry that is neither
XmFONTLIST_DEFAULT_TAG nor an MIT registered charset, the converter creates the compound text for
that segment using the charset (from the registry) and the text of the compound string segment as
an "extended segment" with a variable number of octets per character.
4. If the compound string segment tag is not mapped in the registry, the result is implementation
dependent.
string Specifies a compound string to be converted to compound text.
