1487 dnl -------------------------
1488 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1489 dnl should support line-drawing. Even with Unicode. There is a problem.
1491 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1492 dnl all of those were combined into a page of useful graphics characters.
1494 dnl So far, so good.
1496 dnl However, while they are useful, there are other considerations. CJK
1497 dnl is (because of poor device resolution) often rendered as double-width
1498 dnl characters. So... for these generally-useful characters, what should
1499 dnl be the width (to make them consistent with adjacent characters)?
1501 dnl The obvious choice would have been to make this locale-dependent, and use
1502 dnl wcwidth() to tell applications what the actual width is. That was too
1503 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1505 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1506 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1508 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1509 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1510 dnl instance, it lists half (44/96) of the Latin-1 characters as
1511 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1513 dnl What this means for the implementor is that on some systems wcwidth() can
1514 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1515 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1516 dnl characters). These do not necessarily match the behavior of the terminal
1517 dnl emulator. xterm, for instance, does an optional startup check to find if
1518 dnl this problem (or similar) exists with the system's locale tables, rejecting
1519 dnl them if they are too unreliable.

1698 dnl -----------------
1699 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most

1702 dnl It is ambiguous because the specification accommodated the pre-ANSI
1703 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1704 dnl compiler other than by costly add-ons. Because of this, the specification
1705 dnl did not take into account the use of const for telling the compiler that
1706 dnl string literals would be in readonly memory.
1708 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1709 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1710 dnl That does not solve the problem of using the block of Xt's strings which
1711 dnl are compiled into the library (and is less efficient than one might want).
1713 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1714 dnl when compiling the library and compiling using the library, to tell the
