Hi Kendo support team,
I found a bug (or at least an undesired behavior) in the Kendo Multiselect widget.
After initialization the options in the existing select seem to be rebuilt receiving the content as value attribute if it did not exist before.
During this process potentially existing double spaces are replaced with single spaces (see attached image).
If the options of that select are replaced later, they will keep double spaces.
We use the selected values to receive content from the database, which in these cases is not possible anymore.
Since the content of the database is created by our client, we can't guarantee there might not be any double spaces.
In general I think that the content of the existing options should not be modified in any way.
See the following dojo to reproduce the behavior: https://dojo.telerik.com/oGEcaDoN
