As of man-db 2.5.2, you'll be able to use the '-E UTF-8' option to force
the output encoding. ('man -E' exists in 2.5.1, but I've extended its
semantics.)

Improve 'man -E' to allow overriding the output encoding explicitly,
rather than implicitly (and unreliably) by changing the *roff device
(Debian bug #466396).
* src/encodings.c (device_table): Add stub entries for troff
devices.
(is_roff_device): New function.
* src/encodings.h (is_roff_device): Add prototype.
* src/man.c (options): Change description of -E to allow general
encoding selection.
(parse_opt): Only assign the argument of -E to roff_device if it
is actually a *roff device; otherwise it is presumed to be a true
character encoding and stored in want_encoding. Remove
different_encoding, since testing whether want_encoding is set
supersedes that.
(make_roff_command): If want_encoding is set and is not a *roff
device, recode to it rather than to the locale's encoding.
(display, try_section, display_filesystem, display_database): Test
want_encoding rather than different_encoding.
* man/man1/man.man1 (OPTIONS): Adjust documentation of -E.
* docs/NEWS: Document this.
* src/lexgrog_test.c (options): Bring description of -E into sync
with man.
