1252 dnl -------------------------
1253 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1254 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1255 dnl
1256 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1257 dnl all of those were combined into a page of useful graphics characters.
1258 dnl
1259 dnl So far, so good.
1260 dnl
1261 dnl However, while they are useful, there are other considerations.  CJK
1262 dnl is (because of poor device resolution) often rendered as double-width
1263 dnl characters.  So... for these generally-useful characters, what should
1264 dnl be the width (to make them consistent with adjacent characters)?
1265 dnl
1266 dnl The obvious choice would have been to make this locale-dependent, and use
1267 dnl wcwidth() to tell applications what the actual width is.  That was too
1268 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1269 dnl See for example
1270 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1271 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1272 dnl
1273 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1274 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1275 dnl instance, it lists half (44/96) of the Latin-1 characters as
1276 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1277 dnl
1278 dnl What this means for the implementor is that on some systems wcwidth() can
1279 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1280 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1281 dnl characters).  These do not necessarily match the behavior of the terminal
1282 dnl emulator.  xterm, for instance, does an optional startup check to find if
1283 dnl this problem (or similar) exists with the system's locale tables, rejecting
1284 dnl them if they are too unreliable.
