1397 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1398 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1399 dnl
1400 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1401 dnl all of those were combined into a page of useful graphics characters.
1402 dnl
1403 dnl So far, so good.
1404 dnl
1405 dnl However, while they are useful, there are other considerations.  CJK
1406 dnl is (because of poor device resolution) often rendered as double-width
1407 dnl characters.  So... for these generally-useful characters, what should
1408 dnl be the width (to make them consistent with adjacent characters)?
1409 dnl
1410 dnl The obvious choice would have been to make this locale-dependent, and use
1411 dnl wcwidth() to tell applications what the actual width is.  That was too
1412 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1413 dnl See for example
1414 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1415 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1416 dnl
1417 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1418 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1419 dnl instance, it lists half (44/96) of the Latin-1 characters as
1420 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1421 dnl
1422 dnl What this means for the implementor is that on some systems wcwidth() can
1423 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1424 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1425 dnl characters).  These do not necessarily match the behavior of the terminal
1426 dnl emulator.  xterm, for instance, does an optional startup check to find if
1427 dnl this problem (or similar) exists with the system's locale tables, rejecting
1428 dnl them if they are too unreliable.

1608 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
1609 dnl character-strings.
1610 dnl
1611 dnl It is ambiguous because the specification accommodated the pre-ANSI
1612 dnl compilers bundled by more than one vendor in lieu of providing a standard C
1613 dnl compiler other than by costly add-ons.  Because of this, the specification
1614 dnl did not take into account the use of const for telling the compiler that
1615 dnl string literals would be in readonly memory.
1616 dnl
1617 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
1618 dnl let the compiler decide how to represent Xt's strings which were #define'd.

1620 dnl are compiled into the library (and is less efficient than one might want).
1621 dnl
1622 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
1623 dnl when compiling the library and compiling using the library, to tell the
