mm-with-unibyte-current-buffer
mm-with-unibyte-current-buffer is a Lisp macro in `mm-util.el
'.
(mm-with-unibyte-current-buffer &rest FORMS)
This macro is obsolete since 25.1.
Evaluate FORMS with current buffer temporarily made unibyte.
Equivalent to `progn' in XEmacs.
Note: We recommend not using this macro any more; there should be
better ways to do a similar thing. The previous version of this macro
bound the default value of `enable-multibyte-characters' to nil while
evaluating FORMS but it is no longer done. So, some programs assuming
it if any may malfunction.
