How to enter domains with special characters? (IDNs)
I tried adding a new domain with õ character and I got the following warning.
"Only valid hostname characters are allowed. (a-z, A-Z, 0-9, ., _ and -) Or a single record of '@'. and Name contains invalid characters"
Have you tried using "xn--" instead of the unicode name?
You can use a conversion tool, like this one from Verisign, that will give you the "xn--" that gp mentioned.
