PAText (UTF-8 Version)

Pointing to the previous multi-byte version ("link":http://wiki.qt.io/QPlugs_PAText_Add_Persian_and_Arabic_support_to_WindowsCE_Mobile_applications) the new version comes with improvements and better functionality.

Changes

2.0.0

• Process UTF-8 encoded bytes
• Changed comparison method from "byte to byte" to "byte(s) to table", so even translated chars would be reformatted
• Added isolator function which replaces ligature words
• Fixed the character "ی" problems with Persian layout
• No longer in QPlugs namespace

2.1.0

• Added another Persian 'ی' character to the map table
• Added "detranslate()" function for a reverse action
