some vt100 linedraw characters displayed wrongly

[GoogleCodeExporter]

If the attached file is displayed in UTF-8 mode with a CJK font, some
linedraw characters are displayed incorrectly. Even worse, their display
changes if selected with the mouse.

Hmm, actually this is independent of ambig_wide mode. The root cause is that a 
few
linedraw characters that have lines at different heights are missing from 
Windows
fonts. PuTTY/MinTTY works around that by displaying the horizontal-line 
character
0x2500 a bit higher or lower. Unfortunately that trick is sometimes wrongly 
applied
to neighbouring characters.

Worth considering resurrecting PuTTY's code for drawing the linedraw set 
manually,
because they generally don't always fit together properly anyway with some 
fonts.

Fixed in 0.5 by removing the questionable text height hack and substituting 
similar
linedraw characters that are normally available in Windows fonts.
