special characters when replying

When an email is received with text like "blabla << blabla", and a user replies to this email, then everything after the first blabla is cut off from the quoted text. It seems Roundcube does not handle the "<<" properly. I haven't tried any other characters.

It works fine for me unless I switch from the html editor to plain text editor then the everything after the first word get cut off.
