Routine Description:

    Conversion from CTT to GLYPHSETDATA

Arguments:

    hHeap - Heap handle
    pCTTData - Pointer to the 3.1 format translate table
    dwCodePage - additonal codepage
    pCPSel - symbol set selection command null terminate string.
    pCPUnsel - symbol set selection command null terminate string.
    ppGlyphSetData - Pointer to the GlyphSetData pointer

Return Value:

    If TRUE, function succeeded. Othewise FALSE.

Note:

    Allocates memory from the heap for this.
