1076 dnl -------------------------
1077 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1078 dnl should support line-drawing. Even with Unicode. There is a problem.
1080 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1081 dnl all of those were combined into a page of useful graphics characters.
1083 dnl So far, so good.
1085 dnl However, while they are useful, there are other considerations. CJK
1086 dnl is (because of poor device resolution) often rendered as double-width
1087 dnl characters. So... for these generally-useful characters, what should
1088 dnl be the width (to make them consistent with adjacent characters)?
1090 dnl The obvious choice would have been to make this locale-dependent, and use
1091 dnl wcwidth() to tell applications what the actual width is. That was too
1092 dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
1094 dnl http://www.unicode.org/reports/tr11/tr11-29.html
1095 dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1097 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1098 dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
1099 dnl instance, it lists half (44/96) of the Latin-1 characters as
1100 dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
1102 dnl What this means for the implementor is that on some systems wcwidth() can
1103 dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
1104 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1105 dnl characters). These do not necessarily match the behavior of the terminal
1106 dnl emulator. xterm, for instance, does an optional startup check to find if
1107 dnl this problem (or similar) exists with the system's locale tables, rejecting
1108 dnl them if they are too unreliable.

5809 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
5810 dnl to install symbolic links to the rel/abi versions of shared libraries.

5816 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
5817 dnl (ex: libncurses.so.<ver>).
