Since LiveCode has deprecated functions such as uniCode/uniDecode since version 7, I suggest updating such parts to become aware of newer versions of LC. The same needs to be updated in the documentation

Some of the links given in the source file are outdated and not working any longer. Those references to links need to be updated.
