(Visual FoxPro) Convert a File's Character Encoding from UTF-8 to UFT-8-BOM

To add a utf-8 BOM to a file is just a matter of prepending these 3 bytes to the file: 0xEF 0xBB 0xBF.

This may be difficult in some programming languages, or it may be trivial in either. Therefore, the Chilkat solution you see here might be helpful, or in a language such as C++, the Chilkat solution isn't really necessary because it's easy to do yourself.

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Charset')
loCharset = CreateObject('Chilkat.Charset')

loCharset.FromCharset = "utf-8"
loCharset.ToCharset = "bom-utf-8"

lnSuccess = loCharset.ConvertFile("qa_data/txt/helloWorld.txt","qa_output/helloWorldBom.txt")
IF (lnSuccess <> 1) THEN
    ? loCharset.LastErrorText
    RELEASE loCharset
