[dcplusplus-devel] LinuxDC++: Validate UTF-8 text

[Steven S. <ste...@gm...>]

Currently, if the Text::convert() encounters a conversion where the from and to 
encodings are the same, it returns the initial string with no conversion taking 
place. As I found out, this causes problems where the text that says it is utf-8 
isn't actually valid utf-8. In this case, chat messages would not appear in the 
GUI since GTK+ won't display or convert invalid utf-8. To remedy this, the text 
conversion functions need to validate the text even if their encoding implies 
that no conversion is necessary. I moved these checks into the WIN32 blocks. 
Feel free to delete them altogether if you think you need to validate on windows 
as well.
