ixchSzAlt (1 byte):  An unsigned integer that specifies the zero-based index into the xszFfn. If nonzero, this value specifies the location within xszFfn where xszAlt begins.

panose (10 bytes):  A Panose that specifies font attributes for TrueType fonts.

fs (24 bytes):  A FontSignature, as specified in [MC-FONTSIGNATURE], that specifies the Unicode Subset Bitfields of the font, as specified in [MC-USB], and Code Page Bitfields, as specified in [MC-CPB].

xszFfn (variable):  A null-terminated Unicode string that MUST contain the name of the font.

xszAlt (variable):  A null-terminated Unicode string that specifies the name of an alternative font, intended for font substitution if the font specified by xszFfn is not available. This field, if it exists, begins immediately after the terminating null character of xszFfn. If ixchSzAlt is nonzero, this string MUST exist, otherwise it MUST NOT exist.
