bug#55727: 29.0.50; Incorrect zero symbol transcoding between applications

[Петров Андрей]

Hi, Eli!

Looks like I have to use hex, base64 or other ASCII encodings.
It seems that I will use something like this:

(defun my-escape-char (c)
  (insert (if (< c ?\s) (format "\\%03o" c) c)))

(print "000\000000" 'my-escape-char)


Best regards,
Andrey Petrov.

Done.

Did you consider encoding it in base64?
