================================================================ Dear Bug Team! The docstring for latin-unity-sanity-check says: “This function does _not_ do the safe thing when `buffer-file-coding-system' is nil (= no-conversion). It considers that "non-Latin", and passes it on to the Mule detection mechanism. This could result in corruption. So avoid setting `buffer-file-coding-system' to nil or 'no-conversion or 'binary.” However, when dealing with Unix mail spools, as VM does, it’s the correct and reasonable thing to do to set buffer-file-coding-system to 'binary, since MIME means that identical octets can mean different things in different messages in the same file. I just did a (latin-unity-install) in this XEmacs, without setting the latin-unity-preapproved-coding-system-list. Now, when I visit a VM folder, make a change, and try to save it, I get this: Choose a coding system to save buffer inbox. All preapproved coding systems (buffer-default==binary preferred==utf-16-little-endian-bom) fail to appropriately encode some of the characters present in the buffer. Character sets in the buffer are: control-1 latin-iso8859-1 ascii Please pick a coding system. The following are recommended because they can encode any character in the buffer: iso-8859-1 utf-8 iso-2022-7 ctext escape-quoted Note that if you select a coding system that can not encode some characters in your buffer, those characters will be changed to an arbitrary replacement character, by default `~', on output. [...] (Even when the folder is empty!) I don’t know where it’s getting utf-16-little-endian-bom. 'binary is going to remain equivalent to 'iso-8859-1 for us; it is very unclear to me why latin-unity-sanity-check passes the text on to the Mule detection mechanism when writing, instead of accepting it as a reasonable way of encoding control-1, latin-iso8859-1 and ascii.
