[pyicu-dev] how does one use a .nrm file ?

[Steven R. Loomis]

Hello,
 - you might ask on icu-support as it is an ICU API issue 
<http://site.icu-project.org/contacts>
 - the normalizer2 docs 
<http://icu-project.org/apiref/icu4c/classNormalizer2.html#a5f4be1fb35f18125aea3e3e83373a35f> 
specify that type of usage, which is part of ICU's normal data 
packaging/loading mechanism
 - you might file a bug if the ICU documentation was not clear.

Regards,
Steven
