See more HTML-to-XML/Text Examples

Demonstrates how to convert a string to the GSM character set. For more information about the GSM character set, see GSM Character Set

Note: This example requires Chilkat v9.5.0.79 or greater. Support for the GSM character set was added in v9.5.0.79.

VB.NET

Dim success As Boolean = False

' Demonstrates how to convert a string to the GSM character set byte representation.

Dim s As String = "support@chilkatsoft.com, {abc}"

' In the above string the a-z letters have the same 1-byte values in the GSM character set.
' The '@' character is the 0x00 byte in GSM.
' The curly brace chars are 2-bytes each in GSM -- each beginning with the 0x1B escape char.
' The '.', ' ', and ',' are the same in GSM as us-ascii.

' Let's convert to GSM.

' bdGsm will contain the GSM bytes.
Dim bdGsm As New Chilkat.BinData

' Append the string to bdGsm.  The 2nd arg "gsm" tells AppendString to
' convert the incoming string to the gsm byte representation.
success = bdGsm.AppendString(s,"gsm")

' Let's examine what we have in hex:
Debug.WriteLine(bdGsm.GetEncoded("hex"))

' The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

' Save the GSM bytes to a file.
success = bdGsm.WriteFile("qa_output/gsm.txt")
