Hi, 《ワールドカップ2015》[image: 埋め込み画像 1] Above is a single run of text itemized by ICU's ScriptRun class. It consists of USCRIPT_KATAKANA and USCRIPT_COMMON (cjk punctuations and numbers). When shaping it with top to bottom direction and paint it. As you see the orientation of number "2015"'s glyph is not expected. they should be rotated 90 degrees, but since cjk punctuations which are already rotated by shape process and numbers has same script code, so what is the right way to determine whether a glyph should be rotated or not in vertical writing mode?
