Because you've used double quotes instead of single quotes, the
backslash must be escaped twice: once for the double quote and again
for the replacement.
:help expr-string
:help literal-string
:help s/\\
You could use 2 backslashes if you used a literal string (single
quotes): e.g.,
:echo substitute("String#CHAR","#", '\\#',"g")
