We had this problem since a long time but we couldn't exactly find out that it was caused by the system instead we thought that it was caused by the oversight of our agents. We started to suspect about it being caused by the system recently.

Please inspect the attached images. The string "entire" in the text seems to be normal when editing it but when the agent saves it as a draft it becomes separated as "entir e". This problem doesn't happen all the time and when it happens it does surface only on some strings. It also happens when the reply is being directly sent instead of being recorded as a draft so the drafting process doesn't play any role in this problem.

This is also not a spell checker problem because there aren't any word suggestions such as "entir e" on the spell checker and the browser based spell checker used by our agents are all set as "English (USA)".

The agent who had this "entir e" separation problem did try to re-write the string again and when he did send the message that way then the system did put an extra space character after the corrected "entire" string.
