[gtkmm] converting iso-8859-1 to Glib::ustring

[joey yandle <jwy divisionbyzero com>]

Hi everyone,

After reading through the tutorial and the glibmm docs, I'm still unsure how
to go about converting non-ascii strings to utf8.  Let's say I have
the following:

std::string iso("\xf1");  // iso-8859-1 encoding: n+tilde

How do I make this into a Glib::ustring?  

  Glib::locale_to_utf8(iso);

throws "Invalid byte sequence in conversion input", as does 

  Glib::convert(iso, "", "iso-8859-1");

How do I tell Glib to use a specific encoding when converting?

thanks,
