I have Ubuntu 13.04 from release, fresh installation. System language is Slovak and character encoding is everywhere correct except numbers in Skype and VLC (only in settings, subtitles are encoded correctly)

In Skype are like this:

[١٩:١٣:١٣]
[١٩:١٣:٢٧]
[١٩:١٣:٤٣]
[١٩:١٤:٣٣]

And in VLC

٦ or ٧

So it is the same encoding like in Skype...

Here is a terminal output

play3man@play3man-Extensa-5630:~$ locale
