This your file looks fine with all PDF viewers I've installed on my
system; the lyric tie is taken from the `FreeSerif' font.

I've tried your input file on my box, and here the lyric tie is taken
from the `Sazanami-Mincho-Regular' font (which looks good too, BTW).
In other words, you have to fiddle with the configuration of
FontConfig to get a decent fallback font; this can't be controlled by
lilypond.

Post-mortem, this is not difficult: Just use the --ps option of
lilypond and search for `/uni203F' in the created PS file.

Hmm.  I've the DejaVu fonts installed too, but calling `fc-list', I
can't find an entry for `DejaVuLGC'.  Looking at

  http://dejavu-fonts.org/wiki/Main_Page

I can see that this is a derivative which contains only Latin, Greek,
and Cyrillic glyphs.  And it doesn't contain the undertie `uni203F'!
Uh, oh.  Checking the complete font, `DejaVu Serif' (version 2.32), I
see that it doesn't contain `uni203F' either...

So you should stay with the `FreeSerif' font:

  \override LyricText #'font-name = #"FreeSerif"

It might be worth to extend the `~' feature so that a font can be
specified for this particular glyph, something like

  \override LyricText #'lyric-tie-font = #"..."

given that so many popular fonts are missing it...
