           Summary: Cursor movement in Telugu language
           Product: konsole

Cursor does not move well between characters in Telugu Language in Konsole. I
have tried various fonts, Ubuntu Mono, Nandini, Free Sans, Lohit Telugu.

Reproducible: Always

Steps to Reproduce:
1. Open Konsole 
2. Paste the following text "ఆంధ్ర భారతి తెలుగు, సంస్కృతం నిఘంటువు"
3. Now move the cursor to the left end one character at a time. 

Actual Results:  
The cursor moves between every UTF-8 character including the conjuncts. 

Expected Results:  
Most applications that support Telugu language only allow cursor traversal
between full consonants and vowels. They jump over the conjuncts. But backspace
counts conjuncts. The video attached to the bug shows the issue.

Seems like this issue was discussed as far back as 2003 on KDE. 

"Cursor movement for Indic languages should be restricted to syllable
boundaries. " This is the way it should be done.
