pdutext

Documentation

Overview

Package pdutext provides text conversion for PDU fields.

See 2.2.2 from http://opensmpp.org/specs/smppv34_gsmumts_ig_v10.pdf for details.

pdutext supports Latin1 (0x03) and UCS2 (0x08).

Latin1 encoding is Windows-1252 (CP1252) for now, not ISO-8859-1. http://www.i18nqa.com/debug/table-iso8859-1-vs-windows-1252.html

UCS2 is UTF-16-BE. Here be dragons.

TODO(fiorix): Fix this.

Functions

func Decode

func Decode(typ DataCoding, text []byte) []byte

Decode text.

func Encode

func Encode(typ DataCoding, text []byte) []byte

Encode text.

Types

type Codec

type Codec interface {
	// Type returns the value for the data_coding PDU.
	Type() DataCoding

	// Encode text.
	Encode() []byte

	// Decode text.
	Decode() []byte
}

Codec defines a text codec.

type DataCoding

type DataCoding uint8

DataCoding to define text codecs.
