Is this for all situations where {kEventClassKeyboard, kEventRawKeyDown} is used? I don't use ReceiveNextEvent as the original poster does, but I do install a handler for those raw key downs and then use RAEL. I haven't yet had the time to test my apps under 10.1.3...hopefully this weekend I can look at this stuff.

We think it only happens if:

the app's main event loop uses WNE
someone starts a nested event loop (like Nav does, or the Menu Manager during menu tracking)

Under those circumstances, RawKeyDown keyboard events sent to Carbon event handlers from the nested event loop may contain zero in the MacCharCodes parameter.

If the app uses RAEL, it shouldn't happen.

If this is a "global" problem to carbon events in general, is there any workaround?

I don't know of any at this time, but we'll see if we can think of something.
