Change short day names in Russian

Hello!

How can I fix the short day names displayed in the calendar?

I am using Russian translation, and i have, for example, for Saturday “Су” instead of the correct “Cб”. It is like using “Str” instead of “Sat” in English – doesn’t look very good for the clients.

Changing translation files does not affect the short names for some reason.

Thanks!

Please open /lib/functions/both.php, search for

1	$name[$key] = substr($day, 0, $substr);

and replace it with

1	$name[$key] = htmlentities(substr(html_entity_decode($day), 0, $substr));

Please report if it helped.
Regards
