DEGREE SIGN character in projinfo output is incorrectly displayed on MS Windows console

[agiudiceandrea]

On MS Windows 7 64 bit localized in Italian, the output of projinfo (6.2.1) tool can contain the DEGREE SIGN character (U+00B0 | ° | \xc2\xb0) that is incorrectly displayed in the command prompt console, e.g. the OSGeo4W Shell:

The default console codepage is 850 | ibm850 | OEM Multilingual Latin 1; Western European (DOS)

Is it possible to properly encode/decode the DEGREE SIGN character in the string "Operation n°" or to avoid the use of such character (e.g. using "Operation n.")?
I would also add a space at the end of the string to separate it from the number that follows.

The problem also occurs changing the codepage to 65001 | utf-8 | Unicode (UTF-8) when the font used in the shell is non TrueType (the default font is Raster type).

PROJ/src/apps/projinfo.cpp

Lines 689 to 692 in 529eb50

	std::cout << "Operation n"
	"\xC2\xB0"
	<< (i + 1) << ":" << std::endl
	<< std::endl;

There are many ways to represent this symbol, see https://en.wikipedia.org/wiki/Numero_sign

Normally in English, it's just the two ASCII characters, with an optional fullstop: No.

Going with a plain ASCII representation like "No." would be the simplest fix to this. I have been annoyed by this as well when using projinfo on Windows.
