Better support for Unicode characters in EPUB validator

by Liza Daly

We’ve fixed a long-standing limitation in the online EPUB validator that prevented files with non-ASCII characters from being validated. (The bug was actually not in our code but at a lower level; I’ve posted a fix that simply works around it.)

If you had problems before receiving “Site error” when uploading an EPUB with accented characters, you should now be able to validate successfully.
