1341 dnl -------------------------
1342 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1343 dnl should support line-drawing. Even with Unicode. There is a problem.
1345 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1346 dnl all of those were combined into a page of useful graphics characters.
1348 dnl So far, so good.
1350 dnl However, while they are useful, there are other considerations. CJK
1351 dnl is (because of poor device resolution) often rendered as double-width
1352 dnl characters. So... for these generally-useful characters, what should
1353 dnl be the width (to make them consistent with adjacent characters)?
1355 dnl The obvious choice would have been to make this locale-dependent, and use
1356 dnl wcwidth() to tell applications what the actual width is. That was too
1357 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1359 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1360 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1362 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1363 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1364 dnl instance, it lists half (44/96) of the Latin-1 characters as
1365 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1367 dnl What this means for the implementor is that on some systems wcwidth() can
1368 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1369 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1370 dnl characters). These do not necessarily match the behavior of the terminal
1371 dnl emulator. xterm, for instance, does an optional startup check to find if
1372 dnl this problem (or similar) exists with the system's locale tables, rejecting
1373 dnl them if they are too unreliable.

1552 dnl -----------------
1553 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1554 dnl character-strings.
1556 dnl It is ambiguous because the specification accommodated the pre-ANSI
1557 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1558 dnl compiler other than by costly add-ons. Because of this, the specification
1559 dnl did not take into account the use of const for telling the compiler that
1560 dnl string literals would be in readonly memory.
1562 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1563 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1564 dnl That does not solve the problem of using the block of Xt's strings which
1565 dnl are compiled into the library (and is less efficient than one might want).
1567 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1568 dnl when compiling the library and compiling using the library, to tell the
1569 dnl compiler that String is const.
