πολιτική φιλοσοφία

Now after publishing this post with the post title "politikí̱ filosofía" which is Romanized Greek (greek word using Roman abc alphabets) I will edit the post title to Greek letters πολιτική φιλοσοφία

OK after publication, the permalink (post URL) of this post is
http://testing-blogger-beta.blogspot.com/2010/06/politiki-filosofia.html
unlike when Greek letters πολιτική φιλοσοφία are used for the post title which caused the post title to be the SEO-unfriendly
Greek letters πολιτική φιλοσοφία

OK now I will edit this post and replace with the post title politikí̱ filosofía with Greek letters πολιτική φιλοσοφία and we will then check to reconfirm that there will be no change to the post title which remained the SEO friendly post title like
http://testing-blogger-beta.blogspot.com/2010/06/politiki-filosofia.html

Conclusion

Well folks, testing completed and successful. By first using Latin (Roman) alphabets like "politikí̱ filosofía, publishing, then edit the post title to using Greek alphabets like πολιτική φιλοσοφία, one can have the Greek alphabets in the post title and still get SEO friendly post title.
