unnecessary question mark in Russian translation

here is unnecessary question mark in Main tax zone

it must be Московская область.

I can't fix it by myslef

no, this is not.
I don't add this zone by myself.

I am using Firefox 10.0.1 but this marks appears in the IE9 too.
Windows 7 x64 Professional.
All encoding is UTF8.
Joomla 1.7.4 and Joomla 2.5.1
Last version of Business Hikashop.

Where is this zones stored? In the distribution or in translation packet?

I can delete this question marks but I need to know why this happened.

I have see this question marks in all installations of the Hikashop.
All Russian zones have this marks.

Примо?рский край
Смол?енская о?бласть

and so on....

Here is zone number 3102
Костромска?я о?бласть

(it must be Костромская область)

and here is screenshot of the mysql database in hex format of this record

O, I think that I understand why this happened.
May be because of hosting.
You can see stress mark on the letter "o".
But in Russia we don't use stress mark (emphasis) in the text.
Stress mark using only in school when we learn children how to speak correctly.

Using stress mark in addresses is incorrect. That will have many problems in use.

So I ask you (if it is possible) to remove all stress marks from Russian zones. That's incorrect

p.s.
or you can give me source file and I remove all this letters by myself. This need to be corrected.

ok. I'll do that. Where should I post this file?

here is corrected file.
I have corrected Ukrainian states too. They don't use stress mark too.
