Looks better. There's one more thing that I suggest doing: If a language entry lacks a special character index and no default is explicitly specified, then no special character index (not even 0) should be assigned for that language (in other words, it should be left alone). This will make fonts.tbl parsing more robust in case more language-specific parameters are added to that table in the future.

Another good point, the defaults in Lcl_builtin_languages should be left alone if no special character indexes are specified. I've updated the code again, how does it look now?

I'd put a continue statement in the if statement that checks the value of lang_idx. Other than that, it looks good.
