New to Typophile? Accounts are free, and easy to set up.
Paul has done a very nice thing with the alternate forms in Tourist Gothic.
I quote from the read me:
"Stylistic sets have been designed to use all alternate characters together (set 1), or to apply alternates to one letter (series=all accented variations of that letter) only (sets 2-16)."
This seems very flexible. Now, if only we had a way for apps to report something meaningful in their UI, rather than just "Set 13"!
