@megadix Could you review addition of 8-bit encoding support?

First of all, thank you for your trust in my competencies :) It's been a long time since I don't touch SMS-related stuff, so please forgive me if I'm missing something important...

I've quickly read through the docs as stated in the comment (i.e. SMPP 3.4, GSM 03.38). I see that using a 1111xxxx value is used to send GSM Class Control messages, but I don't understand why enforcing ISO 8859-1. Shouldn't it be encoded in the lower bits? Am I missing something?

You are the author of DataCodingCharsetHandler, you know best :)

GSM 03.38 Section 4 details 1111xxxx and says that 1111x1xx represents 8-bit data. ISO 8859-1 is the encoding that can represent 8-bit binary data, hence the mapping. Did that answer your question?

ISO 8859-1 is the encoding that can represent 8-bit binary data, hence the mapping.

@pchethan 8-bit binary data has no inherent character set. It's just arbitrary binary data. Nonetheless, you no doubt have a use case where doing this makes your code work, for the right or wrong reasons. I'm sure it will help @megadix if you also provide an example of the code that uses this new code you're introducing.
