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.
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.
1259 dnl So far, so good.
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)?
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.
1270 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1271 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
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.
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.

1428 dnl -----------------
1429 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1430 dnl character-strings.
1432 dnl It is ambiguous because the specification accommodated the pre-ANSI
1433 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1434 dnl compiler other than by costly add-ons. Because of this, the specification
1435 dnl did not take into account the use of const for telling the compiler that
1436 dnl string literals would be in readonly memory.
1438 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1439 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1440 dnl That does not solve the problem of using the block of Xt's strings which
1441 dnl are compiled into the library (and is less efficient than one might want).
1443 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1444 dnl when compiling the library and compiling using the library, to tell the
1445 dnl compiler that String is const.
