GSM 03.38 Character Encoding

This module provides transformers for encoding/decoding GSM character sets into/from UTF-8. It relies on interfaces defined by golang.org/x/text/transform package.

More details about the interfaces can be found here.

Character set mapping table was taken from here.

Functions

func NewUnpacker

func NewUnpacker() transform.Transformer

NewUnpacker creates new SevenBitUnpacker.

Types

type Decoder

type Decoder struct {
}

Decoder implements transform.Transformer interface which transforms bytes from GSM to UTF-8 encoding.

func NewDecoder

func NewDecoder() *Decoder

NewDecoder creates new GSM decoder.

func (Decoder) Reset

func (u Decoder) Reset()

Reset implements transform.Transformer interface.

func (Decoder) Transform

func (u Decoder) Transform(dst, src []byte, atEOF bool) (nDst, nSrc int, err error)

Transform implements transform.Transformer interface.

type Encoder

type Encoder struct {
	// contains filtered or unexported fields
}

Encoder implements transform.Transformer interface which transforms UTF-8 bytes into GSM bytes. More details here https://godoc.org/golang.org/x/text/transform#Transformer

func NewEncoder

func NewEncoder(replacement byte) *Encoder

NewEncoder creates new GSM encoder.

func (Encoder) Reset

func (en Encoder) Reset()

Reset implements transform.Transformer interface.
