Problems with encoding and files

Question

Hi friends pls some help my problems is the following
I have a ftp server running on linux and in my program I download files from the ftp server using class specified below.When I download the file content not all content is coming ok. For example I have a string with
Ra�l����1234%#=?[a_@ and when I read content using my methods this part is retirved ok Ra and this one is retrived wrong �����
whith characteres very stranges.
I suppose that the problem is with the encoding, then all day I tried some settings in the class new InputStreamReader.First the encoding UTF-8 because I have created the file using this encoding. Something like this:
in = new InputStreamReader(new GZIPInputStream(localFtp.get(serverFile)),"UTF-8");
but does not work
After I realized that I use the statement localFtp.ascii();
declaring that the content will be downloaded in ascii encoding so
I made this change :
in = new InputStreamReader(new GZIPInputStream(localFtp.get(serverFile)),"US-ASCII");
but still does not work
Please somebody can help me this is very urgent
Here is my code

Answer 1

Err.. GZIP files are not text files so why are you trying to read them using Readers?
