Maybe I'm missing something from your example, previous postings, and my ISP's web mail client, but it appears your desired output doesn't seem to match in character count to your original text. Nevertheless, if all you want is to turn low-ASCII (values less than 0x20) and high-ASCII (values greater than 0x7F) into period characters, you'd find better performance and flexibility for your particular needs by simply writing a function that takes an unsigned 8-bit integer (e.g., in a loop, 0x01, 0x08, 0x0B, ..., 0x13) and returns the desired character. In that function, do your test for low-ASCII and high-ASCII, returning the period character in those cases, and the supplied character in all other cases. Since this code is pretty trivial, you could even inline it rather than code it into a separate function, but I don't know if you need to call it in more than one place in your code.
