Re: Glib::ustring tradeoffs?

[Matthias Kaeppler <matthias finitestate org>]

Thanks for that in-depth answer Chris.

I'd have another question though. First, what's the difference between 
these two conversions:

std::string ascii = "text";

// what's the difference between this ...
Glib::ustring unicode = ascii;

// ... and this?
Glib::ustring unicode = Glib::locale_to_utf8(ascii);

Furthermore, do I have to wrap every line of text into a call to 
Glib::locale_to_utf8()? For example if I define a widget text somewhere, 
do I have to do it like this:

#define WIDGET_LABEL Glib::locale_to_utf8("BUTTON")
...
widget.set_text(WIDGET_LABEL);

and what could happen if I don't make the conversion?

Thanks,
Matthias
