  From "groff-utf8":

# Displays an UTF-8 encoded man page on an UTF-8 text terminal.
# Like "groff", except that it also works for UTF-8 encoded man pages and
# supports a wide range of Unicode characters.
# Prerequisites:
#   - Requires groff-1.18.1 or newer.
# Limitations:
#   - The only supported output devices are "utf8" and "html".
#   - For CJK languages, groff outputs lots of "Can't break line" error
#     messages. This is because groff breaks only at spaces, and Chinese,
#     Japanese, Korean, Thai etc. are written mostly without spaces.
#   - No bidi for Hebrew, Arabic and Farsi is done.
#   - No rendering for Indic languages is done.
# Notes:
#   - For Vietnamese: When using 'less'-381 for viewing, make your terminal
#     window wider than 80 columns. Otherwise 'less' will break lines too
#     early (apparently because it considers many zero-width characters as
#     being of width 1).
#   - For Vietnamese: In xterm, characters with 2 accents are rendered as a
#     hollow box when bold. As a workaround, you can use rxvt, which uses
#     inverse instead of bold.
