urxvt (rxvt-unicode) uses ^?, and xterm could be adjusted to use ^? in

As far as I know LANG is a variable predating the LC_ variables in 
usage, so very few people might know it and not the others, but some 
other people might know LC_* and not LANG.
I think using LC_CTYPE here is better because it's more specific whereas 
LANG is a generic catch-all setting. Someone might set LC_MESSAGES=gr to 
get Greek messages, without caring about the charset here. If that was 
configured with LC_CTYPE, all is well and they can happily coexist, 
getting Greek messages in the terminal charset. If it was configured 
with LANG, it would be overridden and terminal handling would break.
