That's almost certainly not a bug in Debian.  The handing of output
characters with suitable ASCII outputs has changed since the last
release.  As Patrice mentioned, there is a new ASCII_PUNCTUATION
variable that bears on this issue.  @documentencoding used to have
an effect on this (that I thought was clever at the time, but it turned
out not to be), but now ASCII_PUNCTUATION controls the use of ASCII output
for commands like @minus{}.
