-==Known issues==
-=== EiffelStudio IDE===
-* By default, the feature completion dialog (`[Ctrl]+[Space]`) do not show Unicode symbols (including the new across loop symbols). There are 3 solutions to change the behavior:
-** When the completion dialog popups, at the bottom you have a few toggle button for options, including the 5th one to show the Unicode symbols.
-** Change the preference `editor.eiffel.show_completion_unicode_symbols`
-** Change in the `$ISE_EIFFEL/studio/eifinit/default.xml`, the value for the preference `editor.eiffel.show_completion_unicode_symbols` from `False` to `True`.
