Facebook share button has strange label

Facebook share button has strange label:

<span class="pluginButtonLabel">කැමතියි</span>

Label is: " කැමතියි "

How can that happened? Or how can I change it?

Label is like that only when I change site language to Slovenian......

 Check this, I ram into this kind of issues only when I switch to Portuguese  (iso-8859-1) which was in two files (admin-inc.php and design.inc.php) , the correct value is UTF-8. I 

 Thanks for the suggestion, but thi isn't the case. Both files you mentioned have UTF-8 encoding....

My guess is this must be something related directly with FB.... since this happend all of the sudden....

I don't know....

SOLVED

I found this:

in DB table "sys_objects_social_sharing" for Facebook:

<iframe src="//www.facebook.com/plugins/like.php?href={url_encoded}&amp;send=false&amp;layout=button_count&amp;width=450&amp;show_faces=false&amp;action=like&amp;colorscheme=light&amp;font&amp;height=21&amp;locale={locale}" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:100%; height:21px;" allowTransparency="true"></iframe>

and I removed the part: locale={locale}

Slovenian is now correctly shown but it does not change with site language i.e. if I switch to English the FB Like button is in Slovenian.....

If there is locale={locale} then instead sl_SI locale I somehow end up with si_LK which is locale for Shri Lanka.....

Then I checked my language settings and for Slovenian language the code was si witch is not correct, it must be sl. After that the flag for slovenian language was wrong so I renamed /media/images/flags/si.png to sl.png and added back locale={locale} now it is OK. The FB caption is changing with site language and caption for Slovenian language is now shown correctly.
