Hi Mesar,

lou_allround has many options. by default it first uses lou_translate 
and then lou_backTranslate and compares the result. If the 
back-translation matches the original it prints the message "Perfect 
roundtrip!" It's a powerful debugging tool. I would like to know if a 
test using the table I gave produces the same results. I'm not 
comfortable with Python, and I don't want to use ucs4 with liblouis, 
because I run the latest liblouis and liblouisutdml together. ucs4 would 
cause liblouisutdml to use much more memory.

I'm wondering if the internal character representations of Python and 
liblouis could be decoupled. I'm starting to do that with liblouisutdml 
and Java.

John
