When writing into the file, explicitly utf8 encode it, and then try to utf8 decode it on read. If the notes are not valid utf8, we assume they were iso-8859 encoded and return as is. Technically this is a breaking change, since there are iso-8859 comments that would successfully decode as utf8, for example: the byte sequence "C2 A9" would be "£" in iso, but would decode to "£". From what i can tell though, this is rather unlikely to happen for "real world" notes, because the first byte would be in the range of C0-F7 (which are mostly language dependent characters like "Â") and the following bytes would have to be in the range of 80-BF, which are only special characters like "£" (or undefined) Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
