Aha, thank you, that will be a great help. There is another point, though. A Chinese friend recently posted a website for his business. I noticed a few little alterations that had to be made, so I downloaded his source code and pasted it into Notepad. However, when I tried to view the corrections on my browsers, there were obvious formatting errors and the displayed fonts had defaulted to monospace. A warning message came up to say that some characters could not be read. I think this is because the page creation software was originally in Chinese, so eg the font declaration line could not be recognised by my PC browser (although obviously it works OK on the real internet). I may wish to do this exercise again at some time in the future, and as I am learning Chinese, I thought that using a real Chinese computer would help my language skill. Anyway, thank you for the information Ray, it was good of you to help. I shall now go and check out the Google page.
