There's a server at work that name with a non-ascii character. I've run into compatibility issues lots of times where I can't connect. I prefer to just use English with ASCII and be happy
Server names are different. They are by and large machine-facing identifiers, whereas filenames have a 50-50 split of whether they are machine-facing, human-facing, or both. They makes their support of Unicode a much more critical (and appealing) proposition.
