@vindex mm-content-transfer-encoding-defaults
Mapping from @acronym{MIME} types to encoding to use. This variable is usually
@item mail-encode-encoded-word-region
@findex mail-encode-encoded-word-region
Encode the non-@acronym{ASCII} words in the region. For instance,
-@samp{Naïve} is encoded as @samp{=?iso-8859-1?q?Na=EFve?=}.
+@samp{Na@"{@dotless{i}}ve} is encoded as @samp{=?iso-8859-1?q?Na=EFve?=}.
@item mail-encode-encoded-word-buffer
@findex mail-encode-encoded-word-buffer
@example
(mail-encode-encoded-word-string
- "This is naïve, baby")
+ "This is na@"{@dotless{i}}ve, baby")
@result{} "This is =?iso-8859-1?q?na=EFve,?= baby"

@vindex rfc2047-encoded-word-regexp
When decoding words, this library looks for matches to this regexp.
+@item rfc2047-encoded-word-regexp-loose
+@vindex rfc2047-encoded-word-regexp-loose
+This is a version from which the regexp for the Q encoding pattern of
+@code{rfc2047-encoded-word-regexp} is made loose.
+
@item rfc2047-encode-encoded-words
@vindex rfc2047-encode-encoded-words
The boolean variable specifies whether encoded words
-(e.g. @samp{=?hello?=}) should be encoded again.
+(e.g. @samp{=?us-ascii?q?hello?=}) should be encoded again.
+@code{rfc2047-encoded-word-regexp} is used to look for such words.
+
+@item rfc2047-allow-irregular-q-encoded-words
+@vindex rfc2047-allow-irregular-q-encoded-words
+The boolean variable specifies whether irregular Q encoded words
+(e.g. @samp{=?us-ascii?q?hello??=}) should be decoded. If it is
+non-@code{nil}, @code{rfc2047-encoded-word-regexp-loose} is used instead
+of @code{rfc2047-encoded-word-regexp} to look for encoded words.
