I'm getting an interesting (new) error when adding (or editing) entries in Chinese. If the slug is in Chinese I now get the following error:
URI is not a valid URI
It's interesting because I wasn't experiencing that with Craft 2.2. It was allowing me to save entries with Chinese characters in the URI. After upgrading to Craft 2.3.2615 it looks like all Chinese language URIs are now disallowed?
Is this intended behaviour?
