how to compare special characters in string

I have a strings

string='$(0)parameter'

I want to find if '$' is present in the string or not. Can any one tell me how to do that? Using which string functions I can achieve that?

Why is $ special ? It's a normal printable character like 3 or "A" or anything like that so you can use strfind().

If index is empty, $ is not in the string

str='$(0)parameter';
index = strfind(str,'$');

Because i have to search with {"some name": value, this part.
