The docstring for ‘desktop-create-buffer’ calls its first argument
FILE-VERSION. It is reasonable to expect that it’s an integer such as
206.
However, integers are also used as character codes, and 206 is the
character code of Î (U+00CE Latin capital letter I with circumflex).
In the UTF-8 encoding, this character is represented by two bytes 0x81
0xCE.
It is as if under some circumstances the code that saves the desktop
file writes the version as a character code instead of a decimal
integer.
