It seems to work fine for me with a few simple exercises:

  git init repo
  cd repo
  mkdir subdir
  echo foo >'subdir/bar?'
  git add .
  git commit -m 'file with question mark in name'

  git clone --no-local . child
  cd child
  ls -l
  echo changes >'subdir/bar?'
  git commit -am 'changes'
  git show

It also seems to clone fine with jgit:

  jgit clone $PWD/repo jgit-clone

Can you show us more exactly what you're running, and what doesn't work?

Also, one other question: are you sure it's actually a question mark in
the name? If there are non-ascii garbage characters, "ls" will typically
show a question mark when output is going to the terminal. E.g.:

  $ echo foo >"$(printf 'funny\1char')"
  $ ls
  funny?char
  $ ls | cat -A
  funny^Achar$
  $ ls | xxd
  00000000: 6675 6e6e 7901 6368 6172 0a              funny.char.

If it's some more exotic character, then that may be why jgit rejects
it.
