1487 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1488 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1489 dnl
1490 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1491 dnl all of those were combined into a page of useful graphics characters.
1492 dnl
1493 dnl So far, so good.
1494 dnl
1495 dnl However, while they are useful, there are other considerations.  CJK
1496 dnl is (because of poor device resolution) often rendered as double-width
1497 dnl characters.  So... for these generally-useful characters, what should
1498 dnl be the width (to make them consistent with adjacent characters)?
1499 dnl
1500 dnl The obvious choice would have been to make this locale-dependent, and use
1501 dnl wcwidth() to tell applications what the actual width is.  That was too
1502 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1503 dnl See for example
1504 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1505 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1506 dnl
1507 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1508 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1509 dnl instance, it lists half (44/96) of the Latin-1 characters as
1510 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1511 dnl
1512 dnl What this means for the implementor is that on some systems wcwidth() can
1513 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1514 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1515 dnl characters).  These do not necessarily match the behavior of the terminal
1516 dnl emulator.  xterm, for instance, does an optional startup check to find if
1517 dnl this problem (or similar) exists with the system's locale tables, rejecting

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.
