1082 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1083 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1084 dnl
1085 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1086 dnl all of those were combined into a page of useful graphics characters.
1087 dnl
1088 dnl So far, so good.
1089 dnl
1090 dnl However, while they are useful, there are other considerations.  CJK
1091 dnl is (because of poor device resolution) often rendered as double-width
1092 dnl characters.  So... for these generally-useful characters, what should
1093 dnl be the width (to make them consistent with adjacent characters)?
1094 dnl
1095 dnl The obvious choice would have been to make this locale-dependent, and use
1096 dnl wcwidth() to tell applications what the actual width is.  That was too
1097 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1098 dnl See for example
1099 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1100 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1101 dnl
1102 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1103 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1104 dnl instance, it lists half (44/96) of the Latin-1 characters as
1105 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1106 dnl
1107 dnl What this means for the implementor is that on some systems wcwidth() can
1108 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1109 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1110 dnl characters).  These do not necessarily match the behavior of the terminal
1111 dnl emulator.  xterm, for instance, does an optional startup check to find if
1112 dnl this problem (or similar) exists with the system's locale tables, rejecting
