Ok, I've understood this now.
In the meantime, I tried to make my own microtone-uitchtable.
But, unfortunately, it doesn't work.
I always get the error message:
> stefansMikrotoene.ly:32:6: warning: Could not find glyph-name for

I don't understand how to make use of the HE-font, when defining the
alteration signs.
Here is my short snippet:
\version "2.13.3"
\paper{
#(define fonts (make-pango-font-tree "Century Schoolbook L"
"HE"
"Bitstream Vera Sans Mono"
1))
}
HEPitchNames = #`(
(c . ,(ly:make-pitch -1 0 0))
(g . ,(ly:make-pitch -1 4 10/1023))
(edown . ,(ly:make-pitch -1 2 -75/1096))
(bflatseven . ,(ly:make-pitch -1 6 -162/247))
(d . ,(ly:make-pitch -1 1 20/1023))
)
HEStrings = #`(
(0 "\x6e" (0 . 1) (-0.5 . 0.5))
(10/1023 "\x6e" (0 . 0.6) (-0.5 . 0.5))
(-75/1096 "\x6d" (0 . 0.6) (-1.1 . 0.5))
(-162/247 "\x3c\x65" (-2 . 2) (-0.5 . 0.5))
(20/1023 "\x6e" (0 . 0.6) (-1.1 . 0.5))
)
pitchnames = \HEPitchNames
#(ly:parser-set-note-names parser pitchnames)
\relative c' {
c 1 bflatseven
}
