1236 dnl -------------------------
1237 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1238 dnl should support line-drawing. Even with Unicode. There is a problem.
1240 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1241 dnl all of those were combined into a page of useful graphics characters.
1243 dnl So far, so good.
1245 dnl However, while they are useful, there are other considerations. CJK
1246 dnl is (because of poor device resolution) often rendered as double-width
1247 dnl characters. So... for these generally-useful characters, what should
1248 dnl be the width (to make them consistent with adjacent characters)?
1250 dnl The obvious choice would have been to make this locale-dependent, and use
1251 dnl wcwidth() to tell applications what the actual width is. That was too
1252 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1254 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1255 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1257 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1258 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1259 dnl instance, it lists half (44/96) of the Latin-1 characters as
1260 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1262 dnl What this means for the implementor is that on some systems wcwidth() can
1263 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1264 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1265 dnl characters). These do not necessarily match the behavior of the terminal
1266 dnl emulator. xterm, for instance, does an optional startup check to find if
1267 dnl this problem (or similar) exists with the system's locale tables, rejecting
1268 dnl them if they are too unreliable.

1412 dnl -----------------
1413 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1414 dnl character-strings.
1416 dnl It is ambiguous because the specification accommodated the pre-ANSI
1417 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1418 dnl compiler other than by costly add-ons. Because of this, the specification
1419 dnl did not take into account the use of const for telling the compiler that
1420 dnl string literals would be in readonly memory.
1422 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1423 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1424 dnl That does not solve the problem of using the block of Xt's strings which
1425 dnl are compiled into the library (and is less efficient than one might want).
1427 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1428 dnl when compiling the library and compiling using the library, to tell the
1429 dnl compiler that String is const.
