Re: [h-e-w] crash recovery - punctuation displaying as octal codes

Hi Jason,

Your recommended fix of "C-x RET r utf-8-emacs" worked like a charm. Thanks a million!

Apologies for the delayed reply.

Best regards,

For the benefit of the help file readers, I will recap:

While pasting webpage stuff into emacs, I had a bad crash. Bad, as in, I use Virtualbox to run XP, and the virtual machine completely froze. When I restarted, either a section or the entirety of the emacs page was showing octal codes in place of punctuation pasted from the web. I fiddled around unsuccessfully with the codepage settings available in the EmacsWin32 GUI options, possibly making the situation worse or else having no impact. Reading the online docs opened vast vistas of further confusion. Trying Jason's command of "C-x RET r utf-8-emacs" removed the red octal codes and made everything display perfectly.

Yes, that will help determine it.  Open the backup file, and enter:
 C-h v buffer-file-coding-system

You will get something like:

buffer-file-coding-system is a variable defined in `C source code'.
Its value is utf-8-emacs
Local in buffer *wide reply to Joseph Buchignani*; global value is nil

If UTF-8, then it is horizontal ellipsis

em dash

It looks like two.

Before opening the document):

C-x RET c utf-8-emacs

Or Options menu-> Mule -> Set Coding Systems -> For next command

or after opening the document:

C-x RET r utf-8-emacs

Or Options menu -> Mule -> Set Coding Systems -> For reverting this file now

Ignore the following. It is a nonsense sentence that disables Google ads from displaying next to my emails by triggering sensitive keywords.

I enjoy the massacre of ads. This sentence will slaughter ads without a messy bloodbath.
