There has been a lot of talk about "just use UTF-8" or not. Once the hostname was restricted to A-Z,0-9 and -, and it was not allowed to start with a digit. This was later changed so that it was allowed to start with a digit and not to end with a hyphen. Of some reason it is still allowed to have more than one hyphen in a row, even though that does not fit with names. To allow the use UTF-8 one have to change the allowed characters to: A-Z,0-9,-,codes 128-255. As long as programs allow those byte codes and does not change them, all programs can handle hostnames with UTF-8 in them. Does this changing result in more difficulties than the change in allowed hyphens and digits did? Dan
