Triple flats/sharps may be exotic (to say the least), but there's no reason at all why LilyPond shouldn't be able to handle them.
In user discussion thread http://lilypond.1069038.n5.nabble.com/fisisis-impossible-tt210764.html this issue has been brought up (again)...

• new accidental glyphs triplesharp and tripleflat (or flatflatflat? - no, not really...)
• define new constants TRIPLE-FLAT and TRIPLE-SHARP
• add new glyphs to alteration-glyph alist
• new note names in all the languages (sigh...)
• tbd

The chords generated in \chordmode may look over-engineered and one might consider using enharmonic spellings, but currently (without triple accidentals), the output will be plain and simply wrong: withoutany accidental.

Work started.

Hello list,
yesterday I stubled upon a problem with chord transposition.

We had a jazz tune in c major with an a-flat:dim7 chord.

When transposing this tune to e-flat major, lilypond complains
about a missing triple flat and prints a c-flat minor 6/b5
instead (which is enharmonically correct, but ugly to read).

\score {
  \new ChordNames {
    \chordmode {
       as1:dim7
       \transpose c es as:dim7
    }
  }
}

Should we raise an issue for this on the tracker?
Regards, Marc
