Functional Difference from SBCS Open32
N/A.
Implementation
This function returns the CharSet and relating information of the font that has been selected in the specified device context. The Open32 NLS Extension should return the correct CharSet id, which was the result of font mapping process. Please be sure that this result might be different from the CharSet that was specified by application in the LOGFONT structure.
The Codepage Subrange Bitfield (CSB) in the FONTSIGNATUE structure is just filled by translating this CharSet id. See 3.2.4 "The Metrics Mapping" for details.
