Abstract:

Did you ever built a webpage in Homesite and then you didn’t encode the html-entities? Then, probably when the client has a look on it, all the german Umlaut characters look awkward on a mac? And did you figure out why? It’s because of the charsets and the encoding of the characters in the saved file!
