What result do you expect?
`number-to-string' give the string value of a number:
eval:
?\\ ==> 92
(number-to-string ?\\) ==> "92"
`string' will give you the real value of ?char:
eval:
(string ?\\) ==> "\\"
May be a better approach is:(if it is what you expect)
(substring "abcdef\\\\" 0 7)
"abcdef\\"
