I'm still waiting for your explanation of how your scheme for European
diacritics (as used in SE Asia) would work. This thread is intended for
the idea of using the regex to decide which character to take as the
next character from the input trace. In the other thread, I'm still not
sure whether you're working with traces or strings.
