This could come +in handy if the text file includes unusual characters or uses unusual +encoding (@pxref{Coding Systems}). For this purpose, Hexl commands +that insert bytes can also insert @acronym{ASCII} and +non-@acronym{ASCII} characters, including multibyte characters. To +edit a text file with Hexl, visit the file as usual, and then type +@w{@kbd{M-x hexl-mode @key{RET}}} to switch to Hexl mode. You can now +insert text characters by typing them. However, inserting multibyte +characters requires special care, to avoid the danger of creating +invalid multibyte sequences: you should start typing such characters +when point is on the first byte of a multibyte sequence in the file. @node Saving Emacs Sessions @section Saving Emacs Sessions |
