Weird Minecraft "text" ( letters )

When i open minecraft everything that is "text" ( letters etc... ) are really weird and i cant read anything, ill post some screenshots below.
This only happened to me in the latest version ( 1.6.1 ).

EDIT: Oh nevermind i alreday discovered what caused this, it was my 1.5 texture pack that i converted into 1.6 resource pack with texture ender.jar,
Can someone tell me how do i convert it without causing this bug?
