public static String toCharExp(String strRegExp)
```
    Convert a regexp formed with integer charachter into a char formed regexp for instance, "12%12%" which stands for 1 followed by 2 followed by 12 would be misinterpreted by regular regular expression parser. We use here the asci code to encode everything as a single char. Due to char encoding limits, we cannot parse int greater than 2^16-1
    
    Parameters:
    
    strRegExp - a regexp of integer
    
    Returns:
    
    a char regexp
