1477 dnl -------------------------
1478 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1479 dnl should support line-drawing. Even with Unicode. There is a problem.
1481 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1482 dnl all of those were combined into a page of useful graphics characters.
1484 dnl So far, so good.
1486 dnl However, while they are useful, there are other considerations. CJK
1487 dnl is (because of poor device resolution) often rendered as double-width
1488 dnl characters. So... for these generally-useful characters, what should
1489 dnl be the width (to make them consistent with adjacent characters)?
1491 dnl The obvious choice would have been to make this locale-dependent, and use
1492 dnl wcwidth() to tell applications what the actual width is. That was too
1493 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1495 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1496 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1498 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1499 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1500 dnl instance, it lists half (44/96) of the Latin-1 characters as
1501 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1503 dnl What this means for the implementor is that on some systems wcwidth() can
1504 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1505 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1506 dnl characters). These do not necessarily match the behavior of the terminal
1507 dnl emulator. xterm, for instance, does an optional startup check to find if
1508 dnl this problem (or similar) exists with the system's locale tables, rejecting
1509 dnl them if they are too unreliable.

1689 dnl -----------------
1690 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1691 dnl character-strings.
1693 dnl It is ambiguous because the specification accommodated the pre-ANSI
1694 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1695 dnl compiler other than by costly add-ons. Because of this, the specification
1696 dnl did not take into account the use of const for telling the compiler that
1697 dnl string literals would be in readonly memory.
1699 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1700 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1701 dnl That does not solve the problem of using the block of Xt's strings which
1702 dnl are compiled into the library (and is less efficient than one might want).
1704 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1705 dnl when compiling the library and compiling using the library, to tell the
1706 dnl compiler that String is const.

5477 dnl https://www.austingroupbugs.net/view.php?id=523
5478 dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
5480 dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
5481 dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
5483 dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
5484 dnl date unspecified).
5486 dnl + It was adopted in NetBSD make in June 1995.
5488 dnl + The other BSD make programs are derived from the NetBSD make (and for
5489 dnl that reason are not actually different "implementations").
5491 dnl + Some features of NetBSD make were actually adapted from pmake, which
5492 dnl began as a modified GNU make starting in 1993.
5494 dnl + Version 3.8 of the dmake program in January 1992 also implemented this
5495 dnl GNU make extension, but is less well known than the BSD make.
