There is no general way to find out the character encoding of a random piece of data. Some encodings are fairly easy to recognize but the numerous eight-bit encodings can be difficult to tell apart. The character encoding must always be specified somewhere if it isn't implicitly known. In some file systems it's possible to specify the character encoding of a file as an attribute, but I've never seen it used. HTML can contain a meta tag that specifies the encoding, like this: <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> If the HTML file is served by an HTTP server, then the server can specify the encoding in the Content-Type header, and there are rules that define what the encoding is if the server doesn't specify it. You could open the file in a browser that lets you choose the encoding, and try an encoding that you think it may be. Then proofread the text. If all the characters are right, then you guessed right, or close enough to work for that particular file. If not, try the next encoding. > o is there a way to convert this file to UTF-8 Once you know the current encoding, transcoding won't be a big problem. If the encoding is specified in the file, such as in a meta tag, then you'll have to change that too. > or better how to set the default character encoding to utf-8? Default in what context? The locale settings in the environment include a character encoding. Many programs assume that text files and filenames are encoded in that encoding, but some programs think they're smarter and assume something else. (The approach with environment variables will of course fail if different users use different locales and access the same files.) Björn Persson
