1048 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1049 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1050 dnl
1051 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1052 dnl all of those were combined into a page of useful graphics characters.
1053 dnl
1054 dnl So far, so good.
1055 dnl
1056 dnl However, while they are useful, there are other considerations.  CJK
1057 dnl is (because of poor device resolution) often rendered as double-width
1058 dnl characters.  So... for these generally-useful characters, what should
1059 dnl be the width (to make them consistent with adjacent characters)?
1060 dnl
1061 dnl The obvious choice would have been to make this locale-dependent, and use
1062 dnl wcwidth() to tell applications what the actual width is.  That was too
1063 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1064 dnl See for example
1065 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1066 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1067 dnl
1068 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1069 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1070 dnl instance, it lists half (44/96) of the Latin-1 characters as
1071 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1072 dnl
1073 dnl What this means for the implementor is that on some systems wcwidth() can
1074 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1075 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1076 dnl characters).  These do not necessarily match the behavior of the terminal
1077 dnl emulator.  xterm, for instance, does an optional startup check to find if
1078 dnl this problem (or similar) exists with the system's locale tables, rejecting
1079 dnl them if they are too unreliable.
