Internationalized Strings

MongoDB supports UTF-8 for strings in stored objects and queries.  (Specifically, BSON strings are UTF-8.) Generally, drivers for each programming language convert from the language's string format of choice to UTF-8 when serializing and deserializing BSON.  For example, the Java driver converts Java Unicode strings to UTF-8 on serialization. In most cases this means you can effectively store most international characters in MongoDB strings. A few notes: MongoDB regex queries support UTF-8 in the regex string. Currently, sort() on a string uses strcmp: sort order will be reasonable but not fully international correct.  Future versions of MongoDB may support full UTF-8 sort ordering.
