So if apps create Arial font with ANSI_CHARSET, I guess Japanese glyphs will display incorrect on Japanese Windows, just like wine; but on Chinese/Korean Windows, Chinese/Korean glyphs sure display correct.
Please submit your test (with failing tests commented out) to wine-patches, then we can decide whether to make them pass under Wine as is, or ignore (probably broken) behaviour for japanese locale.
