There are some errors that are not fixed such as
1. Looks like you fixed this on your site. It's due to the option "Remove accents from URLs" which now removes all non-ASCII characters (after accents have been converted like é -> e). So for sites in another language like yours, you should have the option off.
2. I don't get that issue here. Have you made modifications to the SnowFlat theme? The HTML for the heading on your site does not match what I have here. The changes in this commit should fix the issue.
