But suppose the application is waiting for a word ending in c-acute.
Unicode conformance rule 9 requires that either U+0107 or U+0063 U+0301
must be accepted. So far so good, although the end-state detector
has to be more complicated.

Remember that this is an ad-hoc situation, where the communicator is
not expecting to talk to a scripting application. This is not a matter
of protocol design, but rather of working with an existing partner
which cannot be easily changed.

If another possible protocol state is triggered by a string ending in
U+0063, then the problem becomes the severe version already described.
