Using current emacs git head, talking to outlook.office365.com over IMAP. Attempts to use gnus-search always fail with the server reporting:
(("NO" ("BADCHARSET" "(US-ASCII)") "The" "specified" "charset" "is" "not" "supported.")) Looking at gnus-search.el, `gnus-search-imap-search-command' always sends CHARSET UTF-8 if the server supports literal+ (which this one does). Sending US-ASCII (or no charset at all) causes the server to return the required results in simple test cases. Is there a way to determine whether a server supports UTF-8 in searches, and adjust the command sent accordingly? If not, could the use of UTF-8 be controlled with (yet another!) variable? Thanks. dme. -- You know, somebody somewhere owes us a favor.
