The implementation of readLine casts each byte read to a Unicode
char and appends it to a buffer. I think this would only work
for reading characters in the ASCII charset (and probably
Latin1). If I used readLine to read Unicode characters, it would
end up splitting each Unicode char into two separate bytes - so
each single Unicode char would end up spread across 4 bytes in
the buffer.
This would be even more of a problem when reading other multibyte
charsets, or single byte charsets that used a different encoding.
Are there plans to add support for other character sets and
encodings to Java (e.g. import and export to and from Unicode)?
