Description

Please describe the problem: cursor moves wrong over bidi text including Arabic-Indic numbers happens for all text input widgets in gtk, including gtk apps such as gedit. I believe the bug is in pango_layout_move_cursor_visually

Steps to reproduce:

1. Start gedit
2. Set keyboard layout to English
3. Enter text, for example: ABC
4. Set keyboard layout Arabic Digits
5. Enter some Arabic letters
6. Enter some Arabic-Indic numbers
7. Hold arrow left down

Actual results: cursor circles around the Arabic letters

Expected results: cursor to move to line start

Does this happen every time? yes
