dealing with extra carriage returns

[sky_diver_]

I use BufferedReader.readLine to process customer's text files.
Occasionally, I get files that terminate each line with CR+CR+LF (two
carriage returns and a linefeed). Every text editor I use treats this a
valid line terminater and displays it as a single line, but the
BufferedReader.readLine method sees each line as two lines.

Would wrapping an InputStreamReader within the BufferedReader be the
best way to get around this problem?

If you know there shouldn't be blank lines, the easiest thing
would be to ignore them. But if you cannot tell, I think you will
have to go 'under' the reader and look directly at the raw data
- read from the InputStream, perhaps making a custom
FilterInputStream that you can wrap with an InputStreamReader.
