1255 dnl -------------------------
1256 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1257 dnl should support line-drawing. Even with Unicode. There is a problem.
1259 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1260 dnl all of those were combined into a page of useful graphics characters.
1262 dnl So far, so good.
1264 dnl However, while they are useful, there are other considerations. CJK
1265 dnl is (because of poor device resolution) often rendered as double-width
1266 dnl characters. So... for these generally-useful characters, what should
1267 dnl be the width (to make them consistent with adjacent characters)?
1269 dnl The obvious choice would have been to make this locale-dependent, and use
1270 dnl wcwidth() to tell applications what the actual width is. That was too
1271 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1273 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1274 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1276 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1277 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1278 dnl instance, it lists half (44/96) of the Latin-1 characters as
1279 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1281 dnl What this means for the implementor is that on some systems wcwidth() can
1282 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1283 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1284 dnl characters). These do not necessarily match the behavior of the terminal
1285 dnl emulator. xterm, for instance, does an optional startup check to find if
1286 dnl this problem (or similar) exists with the system's locale tables, rejecting
1287 dnl them if they are too unreliable.

1431 dnl -----------------
1432 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1433 dnl character-strings.
1435 dnl It is ambiguous because the specification accommodated the pre-ANSI
1436 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1437 dnl compiler other than by costly add-ons. Because of this, the specification
1438 dnl did not take into account the use of const for telling the compiler that
1439 dnl string literals would be in readonly memory.
1441 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1442 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1443 dnl That does not solve the problem of using the block of Xt's strings which
1444 dnl are compiled into the library (and is less efficient than one might want).
1446 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1447 dnl when compiling the library and compiling using the library, to tell the
1448 dnl compiler that String is const.
