- Translates a Unicode character into the corresponding font glyph.\r

- Notes:\r
- This function is only called by Graphics Console module and GraphicsLib. \r

- EDK II provides a UEFI Graphics Console module. ECP provides a GraphicsLib \r
- complying to UEFI HII.\r
- \r
- @param This A pointer to the EFI_HII_PROTOCOL instance.\r
- @param Source A pointer to a Unicode string.\r
- @param Index On input, the offset into the string from which to fetch the character. On successful completion, the \r
- index is updated to the first character past the character(s) making up the just extracted glyph. \r
- @param GlyphBuffer Pointer to an array where the glyphs corresponding to the characters in the source may be stored. \r
- GlyphBuffer is assumed to be wide enough to accept a wide glyph character.\r
- @param BitWidth If EFI_SUCCESS was returned, the UINT16 pointed to by this value is filled with the length of the glyph in pixels. \r
- It is unchanged if the call was unsuccessful.\r
- @param InternalStatus To save the time required to read the string from the beginning on each glyph extraction \r
- (for example, to ensure that the narrow versus wide glyph mode is correct), this value is \r
- updated each time the function is called with the status that is local to the call. The cell pointed \r
- to by this parameter must be initialized to zero prior to invoking the call the first time for any string.\r
-\r
- @retval EFI_SUCCESS It worked.\r
- @retval EFI_NOT_FOUND A glyph for a character was not found.\r
