wxInputStream and multibyte character sets

Hi,

I have a problem with module Wx::Perl::ProcessStream.
This reads the STDOUT from an external process executed using Wx::Process and 
Wx::ExecuteCommand.

To do this it, it does a 'readline' on the wxInputStream available via 
Wx::Process.

My problem is that the implementation of READLINE in Wx::InputStream works as 
follows:

read a char from the stream
append char to a wxString
return wxString if char == '\n'


This appears not to work if the output stream from the external process is, for 
example, UTF-8.

I *think* what perhaps should happen is

read a char from the stream
add it to a charbuffer
if char == '\n' {
    convert charbuffer to a wxString ( method determined by wxWidgets 
unicode/ansi build macros )
    return wxString
}

Alas, my C is too poor to implement / test this (I've tried :-(  ) - I suspect 
it would be v.simple for anyone with adequate C skills.

I have a workaround for the Wx::Perl::ProcessStream module. In that I have 
stopped using readline and do 'read's on the wxInputStream in a perl loop with 
localised byte mode.

This seems to work.

I'm not sure if Wx::InputStream::READLINE needs changing or not. Any thoughts?
