Meaning of “data_coding” field in SMPP

Question

What is the meaning of \"data_coding\" field in the SMPP protocol?

I searched for this but couldn\'t find any helpful resource.

Answer 1

It means how text is converted into bytes, since SMPP is a binary protocol but applications typically deal with text strings. The first hit on google for 'smpp data coding' explains it well http://sourceforge.net/apps/trac/smstools/raw-attachment/wiki/MiscWikiFiles/smppv34_gsmumts_ig_v10.pdf in section 2.2.2.
