1480 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1481 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1482 dnl
1483 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1484 dnl all of those were combined into a page of useful graphics characters.
1485 dnl
1486 dnl So far, so good.
1487 dnl
1488 dnl However, while they are useful, there are other considerations.  CJK
1489 dnl is (because of poor device resolution) often rendered as double-width
1490 dnl characters.  So... for these generally-useful characters, what should
1491 dnl be the width (to make them consistent with adjacent characters)?
1492 dnl
1493 dnl The obvious choice would have been to make this locale-dependent, and use
1494 dnl wcwidth() to tell applications what the actual width is.  That was too
1495 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1496 dnl See for example
1497 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1498 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1499 dnl
1500 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1501 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1502 dnl instance, it lists half (44/96) of the Latin-1 characters as
1503 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1504 dnl
1505 dnl What this means for the implementor is that on some systems wcwidth() can
1506 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1507 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1508 dnl characters).  These do not necessarily match the behavior of the terminal
1509 dnl emulator.  xterm, for instance, does an optional startup check to find if
1510 dnl this problem (or similar) exists with the system's locale tables, rejecting

1692 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most

1694 dnl
1695 dnl It is ambiguous because the specification accommodated the pre-ANSI
1696 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1697 dnl compiler other than by costly add-ons.  Because of this, the specification
1698 dnl did not take into account the use of const for telling the compiler that
1699 dnl string literals would be in readonly memory.
1700 dnl
1701 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1702 dnl let the compiler decide how to represent Xt's strings which were #define'd.

1707 dnl when compiling the library and compiling using the library, to tell the

10152 dnl or adapt to the vendor's definitions to get equivalent functionality,

10155 dnl Parameters:
10156 dnl     $1 is the nominal value for _XOPEN_SOURCE
10157 dnl     $2 is the nominal value for _POSIX_C_SOURCE
10158 dnl
10159 dnl The default case prefers _XOPEN_SOURCE over _POSIX_C_SOURCE if the
10160 dnl implementation predefines it, because X/Open and most implementations agree
10161 dnl that the latter is a legacy or "aligned" value.
10162 dnl
10163 dnl Because _XOPEN_SOURCE is preferred, if defining _POSIX_C_SOURCE turns
10164 dnl that off, then refrain from setting _POSIX_C_SOURCE explicitly.
