I want to check only a few special charaters in a string.
For example this "FTO – Gen 3.1 Device – Ref No 11936 – LED" string contains – (en-dash)
And I want to remove and replace it with another string if such type of special char appears in the string.
Below special char I want to check if its present the string
\,{,^,},%,`,],>,[,~,<,#,|,
I have listed all of the special char above
Don’t know much about regex that how I can get a match only sting contains the above special char.
Your help is much appreciated.

Try this:
[\\{\^}%`\]>\[~<#|]

Explanation
The two outermost brackets ([...]) are a character class, which means that anything inside them will match.
Some characters are reserved, and so need to be escaped with a backtick. This is because RegEx uses these characters in its grammar. These characters are: \\, \^, \], and \[ (in this case). The rest just appear in the class as-is.
