[Bugfix] FS#12436 cache mode strings prior to font disable

Browse source 
by checking string len we can cache the USB hid mode strings

I guess if the user doesn't have enough glyphs they might still
might not get the whole thing but this appears to work with
50 glyphs and the referenced russian language selected

remove call to  GUI_EVENT_ACTIONUPDATE it is now counterproductive
