Sorry, my writing was bad. My quotation is a part of Unicode Standard Annex #11 EAST ASIAN WIDTH. Please see "When processing or displaying data" of "5 Recommendations" at http://www.unicode.org/unicode/reports/tr11/ . > If everybody agrees to this suggestion, here's the patch. Is the name of modifier prefix "cjk-" good? It influences not CJK characters but a part of symbols and European characters. Please refer to Andy's opinion: http://cygwin.com/ml/cygwin/2009-06/msg00240.html It personally proposes "ambinarrow" because the switch of Vim is "ambiwidth". And, I don't think that it is symmetrical. How about the following patch?
