Lute tablature and "j"

[William Bajzek]

Hello. I'm new to the list, but I've been using Lilypond for about a year now. 

Recently I've been wanting to produce some lute tablature, and just noticed the 
example in the documentation on doing letter tablature. I tried it out and 
found a problem that I'm not sure how to get around; the style of lute 
tablature I am interested in writing (a la Luys de Narvaez) skips the letter j 
as a fret indicator. Can anyone recommend a way to accomplish that in Lilypond?

Apologies if this has been covered. I couldn't find it in the archives.
