Thanks, Levente
 
Your first example worked fine for me! So latin1 is the encoding expected by many existing applications?

Here is an example using Latin1 encoding and #crlf line end conversion. 
That means that every #cr will actually be written as crlf:

FileStream newFileNamed: 'yourNewLatin1EncodedFile' do: [ :file |
 	file
 		lineEndConvention: #crlf;
 		converter: Latin1TextConverter new;
 		nextPutAll: 'This is an example sentence with some Latin1 compatible characters: áéíóúöü.'; cr;
 		nextPutAll: 'This is a second example sentence.'; cr ].

If you don't set the line encoding it will not convert line endings. If you don't set the converter, it will use an UTF8TextConverter.
If you start your file with a Byte Order Mark, then most software will assume that it has UTF-8 encoding. The following example uses UTF-8 encoding and no conversion for line ending, it also writes BOM at the
beginning:

FileStream newFileNamed: 'yourNewUTF8EncodedFile' do: [ :file |
 	file binary.
 	UTF8TextConverter writeBOMOn: file.
 	file
 		ascii;
 		nextPutAll: 'This is an example sentence with some Latin1 compatible characters: áéíóúöü.'; crlf;
 		nextPutAll: 'This is a second example sentence.'; crlf ].

(Note that sending #crlf to a Stream only works if you're using a 4.1
image.)

If you really want the old way, use StandardFileStream instead of FileStream, but that will only work octet characters and byte strings.
