1017 dnl -------------------------
1018 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1019 dnl should support line-drawing. Even with Unicode. There is a problem.
1021 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1022 dnl all of those were combined into a page of useful graphics characters.
1024 dnl So far, so good.
1026 dnl However, while they are useful, there are other considerations. CJK
1027 dnl is (because of poor device resolution) often rendered as double-width
1028 dnl characters. So... for these generally-useful characters, what should
1029 dnl be the width (to make them consistent with adjacent characters)?
1031 dnl The obvious choice would have been to make this locale-dependent, and use
1032 dnl wcwidth() to tell applications what the actual width is. That was too
1033 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1035 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1036 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1038 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1039 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1040 dnl instance, it lists half (44/96) of the Latin-1 characters as
1041 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1043 dnl What this means for the implementor is that on some systems wcwidth() can
1044 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1045 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1046 dnl characters). These do not necessarily match the behavior of the terminal
1047 dnl emulator. xterm, for instance, does an optional startup check to find if
1048 dnl this problem (or similar) exists with the system's locale tables, rejecting
1049 dnl them if they are too unreliable.

5711 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure

5718 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5719 dnl (ex: libncurses.so.<ver>).
