Overview ¶
Package pdu implementes dataencoding schemes described in 3GPP TS 23.040. Such schemes include: GSM 7-Bit text encoding, UCS2 (UTF-16) text encoding, semi-octet encoding of integers.

Constants ¶
const CR byte = 0x0D
CR <CR> code.
const Esc byte = 0x1B
Esc code.
const Sub byte = 0x1A
Sub Ctrl+Z code.
Variables ¶
var ErrUnevenNumber = errors.New("decode ucs2: uneven number of octets")
ErrUnevenNumber happens when the number of octets (bytes) in the input is uneven.
var ErrUnexpectedByte = errors.New("7bit decode: met an unexpected byte")
ErrUnexpectedByte happens when someone tries to decode non GSM 7-bit encoded string.
Functions ¶
func Decode7Bit ¶
Decode7Bit decodes the given GSM 7-bit packed octet data (3GPP TS 23.038) into a UTF-8 encoded string.
func DecodeSemi ¶
DecodeSemi unpacks numerical chunks from the given semi-octet encoded data.
func DecodeSemiAddress ¶
DecodeSemiAddress unpacks phone numbers from the given semi-octet encoded data. This method is different from DecodeSemi because a 0x00 byte should be interpreted as two distinct digits. There 0x00 will be "00".
func DecodeUcs2 ¶
DecodeUcs2 decodes the given UCS2 (UTF-16) octet data into a UTF-8 encoded string.
func Encode7Bit ¶
Encode7Bit encodes the given UTF-8 text into GSM 7-bit (3GPP TS 23.038) encoding with packing.
func EncodeSemi ¶
EncodeSemi packs the given numerical chunks in a semi-octet representation as described in 3GPP TS 23.040.
func EncodeUcs2 ¶
EncodeUcs2 encodes the given UTF-8 text into UCS2 (UTF-16) encoding and returns the produced octets.
