1464 dnl -------------------------
1465 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1466 dnl should support line-drawing. Even with Unicode. There is a problem.
1468 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1469 dnl all of those were combined into a page of useful graphics characters.
1471 dnl So far, so good.
1473 dnl However, while they are useful, there are other considerations. CJK
1474 dnl is (because of poor device resolution) often rendered as double-width
1475 dnl characters. So... for these generally-useful characters, what should
1476 dnl be the width (to make them consistent with adjacent characters)?
1478 dnl The obvious choice would have been to make this locale-dependent, and use
1479 dnl wcwidth() to tell applications what the actual width is. That was too
1480 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1482 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1483 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1485 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1486 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1487 dnl instance, it lists half (44/96) of the Latin-1 characters as
1488 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1490 dnl What this means for the implementor is that on some systems wcwidth() can
1491 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1492 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1493 dnl characters). These do not necessarily match the behavior of the terminal
1494 dnl emulator. xterm, for instance, does an optional startup check to find if
1495 dnl this problem (or similar) exists with the system's locale tables, rejecting
1496 dnl them if they are too unreliable.

1675 dnl -----------------
1676 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most

1679 dnl It is ambiguous because the specification accommodated the pre-ANSI
1680 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1681 dnl compiler other than by costly add-ons. Because of this, the specification
1682 dnl did not take into account the use of const for telling the compiler that
1683 dnl string literals would be in readonly memory.
1685 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1686 dnl let the compiler decide how to represent Xt's strings which were #define'd.
1687 dnl That does not solve the problem of using the block of Xt's strings which
1688 dnl are compiled into the library (and is less efficient than one might want).
1690 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1691 dnl when compiling the library and compiling using the library, to tell the
1692 dnl compiler that String is const.
