Yes. That's the correct behavior, and this is (was) a bug. The fix is at 
GitHub in update 6523.

It is an usually unused code, that in Cuis we use for the 
assignmentArrow. See #smalltalkLeftArrow and #smalltalkUpArrow. We 
convert those to ':=' and '^' when saving code to files or exporting to 
clipboard. In #6523 I added the conversion to Workspace saving, that was 
missing.

Thanks for the report!
