Right, in principle. However, it should be ok to include noncharacters in CLDR data files for processing by CLDR implementations, and it should be possible to edit and diff and version-control and web-view those files etc. It seems that trying to define "interchange" and "public" in ways that satisfy everyone will not be successful. The FAQ already gives some examples of where noncharacters might be used, should be preserved, or could be stripped, starting with "Q: Are noncharacters intended for interchange? <http://www.unicode.org/faq/private_use.html#nonchar6>" In my view, those Q/A pairs explain noncharacters quite well. If there are further examples of where noncharacters might be used, should be preserved, or could be stripped, and that would be particularly useful to add to the examples already there, then we could add them. markus
