Well,I must have written the problem with the coded text a bit confusing ...Sorry for this..
Well what I wanted to say is that:
When I open my Web Browser (Mozilla) and type localhost/egroupware and then sign in egroupware,, I don't have any problem when I'm writing-translating in the developer tools.There everything is right.The greek text appears normally.
My problem appears when I follow the path C:\ ....\egroupware\calendar\setup\phpgwapi_el.lang in the egroupware folder that has been created during instalation.(The phpgwapi_el.lang is in the egroupware Root file )
When I click on the phpgwapi_el.lang of each application's setup folder (-let's say calendar-) It shows ##and numbers.
This encoded text I want to be able to see in normal greek text instead of encoded.
