That may be a violation of RFC3501 Sec. 5.1, which strictly defines 
mailbox names as 7-bit. There is a defined mechanism for representing 
non-ASCII characters in mailbox names using a modified UTF-7 encoding, 
but it has historically had flawed support in both clients and servers. 
There is also an extension defined for general UTF-8 support including 
mailbox names, but servers that support it must be explicitly told to 
enable UTF-8 by an IMAP client before they send that client UTF-8 
strings. As a practical matter, it is very risky to use non-ASCII 
characters in mailbox names in an account that is used with diverse 
clients because there is a diversity of incorrect implementations of 
both of those mechanisms across clients and servers.

Which is clearly a worse flaw than AltaMail asking the server to use 
non-ASCII characters in a mailbox name or the server doing so. There is 
a recommended handling of 8-bit names which does not include any words 
like "crash" or "miserably." :)

You are fortunate to have a responsive provider.
