libpostal logs "invalid UTF-8" warning for a string having "\0" or "\u0000" and stays in waiting state

Using the jpostal, if I call jpostal parseaddress like:

AddressParser.getInstance().parseAddress("Rue du Médecin-Colonel Calbairac Toulouse France\u0000")

I am seeing this warning logged

WARN  invalid UTF-8
   at transliterate (transliterate.c:791) errno: No such file or directory
WARN  invalid UTF-8
   at transliterate (transliterate.c:791) errno: No such file or directory

   at transliterate (transliterate.c:791) errno: No such file or directory
WARN  invalid UTF-8
   at transliterate (transliterate.c:791) errno: No such file or directory

And the thread remains in waiting state.. This happens only when the address have \u0000 or (simple \0) character in it. Simplest solution seems to not send \0 character or replace it before calling parseAddress...

@myasirkhan I hit this too, I've stolen the above example in some of the tests for a PR I just created
