Those settings should work (the important ones are LC_ALL and LC_CTYPE, LANG).
There is a line called "line-drawing characters" which is *not* turned on. It is unclear to me what this does (see the xterm man page for an explanation, which is not totally clear). What it might be doing is turning on the line-drawing characters from X itself, to replace the ones which are provided by the font, or alternatively what it might be doing is enabling the line-drawing characters which are already provided by the font. As I said, the explanation in the man page is not very clear and these two meanings are obviously opposite to each other. In any event, to toggle this setting on and off all by itself, when other settings are not changed, seems to have no effect. There are also lines in that menu for UTF-8 Encoding, UTF-8 Fonts, and UTF-8 Titles. These are also apparently not turned on (no check marks in front). Setting UTF-Encoding *and* UTF-8 Fonts *and* Line-Drawing Characters all to be on seems to solve the problem. But by default all three of them are turned off. Why are all three of these settings turned off by default? I have no
Line-Drawing is normally turned off because a well-designed font will look better than xterm's built-in equivalent (since it may use thick lines for large characters). UTF-8 Fonts would be turned on if you used the "uxterm" shell script to setup xterm, which gives better coverage of Unicode. UTF-8 Encoding isn't on either because there's some problem with the locale _tables_ or due to a resource setting. If you have "appres" installed, you may see the problem in the output of "appres XTerm".
idea. In particular, this is even more amazing because it seems to be in conflict with the locale settings displayed above. So, in order to get back to the bottom of this problem it seems to me that what needs to be done is to set up a way to turn all three of these settings on. However, I do not know what I am supposed to do in order to carry that out. Change some configuration file, I suppose, or else do a local override. But I suspect that the settings are already set correctly in some file somewhere and that somehow the settings in that file are being ignored.
I'd try using the "uxterm" script (it's supposed to do most of the fixes you need). -- Thomas E. Dickey <dickey invisible-island net> http://invisible-island.net ftp://ftp.invisible-island.net
