[galaxy-dev] substitution of special characters in arguments of galaxy tools

Dear galaxy developers, Galaxy seems to substitute special characters when it passes arguments to its tools (e.g. the content of input fields of type 'text'). In general, this is useful. However, '%' is substituted by 'X', i.e. the substitution is not invertible which can be a real show stopper. Is there some way to change this substitution or switch it of completely?
