So... for these generally-useful characters, what should dnl be the width (to make them consistent with adjacent characters)? dnl dnl The obvious choice would have been to make this locale-dependent, and use dnl wcwidth() to tell applications what the actual width is. That was too dnl obvious. Instead, we have a slew of "ambiguous-width" characters. dnl See for example dnl http://www.unicode.org/reports/tr11/tr11-29.html dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html dnl dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For dnl instance, it lists half (44/96) of the Latin-1 characters as dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous. dnl dnl What this means for the implementor is that on some systems wcwidth() can dnl give bad advice. On Solaris, some of the ambiguous widths are returned as dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing dnl characters). These do not necessarily match the behavior of the terminal dnl emulator. xterm, for instance, does an optional startup check to find if dnl this problem (or similar) exists with the system's locale tables, rejecting dnl them if they are too unreliable.
