[orca-list] Copy flat review and append flatreview to clipboard does not take multibyte characters into account

[Peter Vágner <pvdeejay gmail com>]

Hello,

This is difficult to explain, but there are various issues when trying 
to copy other than english texts from flat review.

Steps to reproduce
1) Open gedit
2) Paste a bunch of random multibyte characters inside an empty document 
e.g.
+ľščťžýáíé=
3) Notice the string above is 11 characters long and ends in = [equals] 
character.
4) Explore the gedit window using the flat review also trying to copy 
the line where this string has been pasted using copy flat review command.
5) Make a new empty line and try to paste what you just have tried to 
copy in the previous step.
6) Notice the string you have just pasted is different from the one you 
have copied. It's only 6 characters long
+ľščťž


Also there appear to be more complicated issue I can't explain how it 
might happen.

Paste a few following lines into the gedit:
detský tábor
jazykový tábor
jazykový pobyt

Try to copy the first and append second and third line via flat review. 
When pasting you will get...
detský tábo
jazykový tá
jazykový p

In this case the shortened pasted lines do not even corespond with 
string length minus number of the multibyte characters, so this must be 
something different not in order.

The same thing can be reproduced when copying from any flat review e.g. 
terminal as well.

It's very rare I need to copy other than english texts this way, so I 
can't really say whether this is recent or not.
I might be able to test some earlier versions later to at least find out 
whether this is recent.

Thanks and greetings

Peter
