Lo and behold, this is what the SFTP v6 spec says [1]: The preferred encoding for filenames is UTF-8. This is consistent with IETF Policy on Character Sets and Languages [RFC2277] and it is further supposed that the server is more likely to support any local character set and be able to convert it to UTF-8. However, because the server does not always know the encoding of filenames, it is not always possible for the server to preform a valid translation to UTF-8. When an invalid translation to UTF-8 is preformed, it becomes impossible to manipulate the file, because the translation is not reversible. ...
