I was referring to the fact that besides xterm, there are other components which can produce the problem (the font files, the libraries reading the font files and the locale support). FreeBSD's had problems with locale support for quite a while, plus freetype2 has made changes. But "font metrics" refers to the size of the glyphs in a font-file which are stored in its header (and which freetype2 and/or fontconfig can (mis)interpret). =20 > > > However, if I specify a font with '-fn 10x20' on the xterm invocation= I don't > > > get the gratuitous spaces. > >=20 > > that's consistent with my remark above. > >=20 > > Also, it's possible (I suppose) that the change to use Unicode 10 > > last spring is aggravating the problem, but I'd have to study an > > example to see exactly why. >=20 > Is there some way that I could revert that change or configure xterm to > not use it? I took a quick look for "downgrade freebsd package", and didn't see anything obvious. For development, I've adapted the port-files from FreeBSD in xter= m's sources, and have used those in my ports tree. So what I'd do to get/test and older version of xterm would be to tweak the PORTVERSION in the Makefile (and checksums) using /usr/ports/x11/xterm as a starting point. Something like cd /usr/ports/x11/xterm sudo make to get the dist-files for the current version on the disk, then copy the version of "xterm-XXX.tgz" from ftp://ftp.invisible-island.net/xterm/ to cd /usr/ports/distfiles and sudo vi Makefile to change the PORTVERSION number, and referring to https://www.freebsd.org/doc/en/books/porters-handbook/porting-checksum.html sudo make makesum sudo make clean sudo make sudo make install The change to use Unicode 10 was in xterm #330, so you might consider #329. --=20 Thomas E.
