I’ve got some issues here. I want to let everybody know, that the issues are between two free hosters, apriori possibly crappy, but I’m trying to resolve this situation, and learn in the process, because I have virtually no experience in this.
- The site is UTF-8 encoded. The MySQL is UTF-8 encoded as well. Majority of the blogposts are in Russian (cyrillic). So, the site works fine (when it works), no problem with content. However, what bugs me is the representation of the content in DB. If I access DB through phpMyAdmin, all the fields with cyrillyc posts, comments, etc. show up in a mumbo jumbo like that: Ð¾Ð¾Ð±Ñ‰Ðµ Ð¾Ñ‡ÐµÐ½Ñ.
I also noticed, that “collation” field in wp_ tables have value of latin1_swedish_ci. What is collation in DB terms, and why it has such peculiar choice of value?
- So, if I backup DB dump as a .sql text file on my machine it shows same Ð¾Ð±Ñ‰Ðµ Ð¾Ñ‡Ð in the text editor. So same way it shows in the other server’s DB after import.
Now, the interesting thing starts. After import I access website, and most of the content is fine, but some of it is corrupt. It’s only certain letters that are corrupt (I confirmed a few: small (с), (э), (я), and capital (А) and (Н)).
For instance, phrase “тест, тест, тест” (test, test, test) turns into “те�?т, те�?т, те�?т” on the site itself, and in the RSS-feed.
You can see it here: http://eugkra.freehostia.com/travel/arizona/home/ (it’s a test site for now (since I’m not transferring domain, till I figure this out), so feel free screwing with it).
- However, note, that second comment shows up correct. That’s because I posted it on the new host, so all the new content will show up correct.
But yet again another peculiarity: both of this comments show up in DB absolutely identical with the value of “Ð¢ÐµÑ?Ñ‚, Ñ‚ÐµÑ?Ñ‚, Ñ‚ÐµÑ?Ñ‚.”.
So, what can cause all this? Could it be phpMyAdmin issue? Could it be MySQL misconfiguration on one (or both) of the hosts? Is it purely encoding mismatch, or some internal bug in WP? Is it at all typical? How do non-latin characters are being recorded in other peoples’ BD? Why is collation set to Swedish?
P. S. The MySQL version on the first host is 4.0.24, on the second — 4.1.11-Debian_4sarge7. WP version 2.1.
