1446 dnl -------------------------
1447 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1448 dnl should support line-drawing. Even with Unicode. There is a problem.
1450 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1451 dnl all of those were combined into a page of useful graphics characters.
1453 dnl So far, so good.
1455 dnl However, while they are useful, there are other considerations. CJK
1456 dnl is (because of poor device resolution) often rendered as double-width
1457 dnl characters. So... for these generally-useful characters, what should
1458 dnl be the width (to make them consistent with adjacent characters)?
1460 dnl The obvious choice would have been to make this locale-dependent, and use
1461 dnl wcwidth() to tell applications what the actual width is. That was too
1462 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1464 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1465 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1467 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1468 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1469 dnl instance, it lists half (44/96) of the Latin-1 characters as
1470 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1472 dnl What this means for the implementor is that on some systems wcwidth() can
1473 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1474 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1475 dnl characters). These do not necessarily match the behavior of the terminal
1476 dnl emulator. xterm, for instance, does an optional startup check to find if
1477 dnl this problem (or similar) exists with the system's locale tables, rejecting
1478 dnl them if they are too unreliable.

1657 dnl -----------------
1658 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1659 dnl character-strings.
1661 dnl It is ambiguous because the specification accommodated the pre-ANSI
1662 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1663 dnl compiler other than by costly add-ons. Because of this, the specification
1664 dnl did not take into account the use of const for telling the compiler that
1665 dnl string literals would be in readonly memory.
1667 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1668 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1669 dnl That does not solve the problem of using the block of Xt's strings which
1670 dnl are compiled into the library (and is less efficient than one might want).
1672 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1673 dnl when compiling the library and compiling using the library, to tell the
1674 dnl compiler that String is const.
