Most of my post titles on my blog use foreign language text which requires Unicode to show up correctly. When I post with a foreign language title all the Unicode characters are completely deleted from the permalink and I'm left with something generic like "post-6.html". What can I do? I'm using Blogger in the United States.
From Blogger Post Editor, you can customize your posts with custom permalinks setting. If you prefer to use a custom permalink, you can do so via the “Permalink” option in the Post Settings box.
example www.nameofblog.blogspot.com/2012/06/post-6.html .
The bolded area is the portion of the URL that is customizable.
If the custom permalink you entered already exists, Blogger will attempt find a free one for you.
At present, the characters allowed in a custom URL are limited to: a-z, A-Z, 0-1. The only special characters available are underscore, dash, and period.
You can read here for more details about it.
I do not believe there is any way to make Blogger do this.
