Yes, I was unhappy with all this special cases LY_BOLD_*, LY_SOFT_HYPHEN,
backspaces (no idea about it et all) and such.

Perhaps a better idea is using of second temp file: read the result of
print_wwwfile_to_fd() and convert it via LYUCTranslateBackFormData()
line-by-line, but you decide this as a complication...
Now when you invent a higher level conversion function we have no problem with
utf-8 charset if any.

The explanation given in lynx.cfg: there are many d.c.s. possible and (remote)
mail agent may not recognize iso-8859-4 or cp866 or other uncommon charsets.
Some kind of approximation would not be too bad - lynx have already done the
conversion to d.c.s. ("internal" charset) - why not to convert it more if
necessary? Anyway, the approximation is more readable than garbage.

In my particular case - d.c.s=cp866 which is generally not recognized
by mail agents, but windows-1251 and koi8-r are.
(also, 128-159 characters got stripped from the subject line
by my mail provider; windows-1251 and koi8 keep letters out of this range).

Sure, we need a proper charset mail header.
