Look inside. See that you can do this other ways too. Apparently the AscII codes are different or do not work at all in Windows 10. So this may not work if you have Windows 10. Also note that in different countries the first 128 AscII characters may be different.
This was done in windows. If you are using a Mac or Linux it may be different. Also note that some browsers may affect things so it possibly might not work in those, but it should. It should work otherwise, barring unforeseen circumstances. ;)
