If the system won't pass-through UTF8 cleanly, encode the strings with either UTF7 or Punycode. We should probably decide which one people prefer. For example, String: Zürich punycode: xn--Zrich-kva UTF-7: Z+APw-rich UTF-7 is probably simpler to understand. Punycode is really wierd, but has been adopted for domain names. Punicode is probably more compact with strings with more non-ascii characters in it (but it is longer in the above example). Which would people prefer to see used to allow OSM data to be round tripped outside Unicode (or binary 8-bit clean) environments?
