[PATCH 0/1] MR6385: gdi32: Fix the text's charset error in obtaining from meta dc.

[JiangYi Chen (＠meshine)]

Log: get_dc_attr always failed for meta dc,so GdiGetCodePage always
return CP_ACP. And GetTextCharset is similar to this situation.
Finally, leading to an error result of text_mbtowc call by ExtTextOutA
and an error result of METADC_ExtTextOut.
