Internal error when trying to save kn_IN letters

[vincentvikram@…]

Steps to reproduce the error:

1. I tried to save a section which had a kn_IN script characters and obtained the below error.
2. Removed the offending language characters and the content was saved.
3. Tried to paste the characters here and the bug report reported a bug :)

Error Reproducible.
