This version does not yet support codepages 437 and 850 completely.

I guess I should have included more details in #142, but the missing characters are not easy to generate with easy to reproduce steps in cmd.exe.

The last missing glyphs are in the characters for values 0x01 to 0x1F, which are typically used as C0 control characters, but can be output as characters by CUI apps that directly control the screen buffer.

The same characters with Consolas font:

So for complete compatibility with older CUI apps, the following characters are also required:

Hex 0123456789ABCDEF
0_ ☺☻♥♦♣♠•◘○◙♂♀♪♫☼
1_ ►◄↕‼¶§▬↨↑↓→←∟↔▲▼

Their Unicode codepoints are as follows:
0_ : (NULL), U+263A, U+263B, U+2665, U+2666, U+2663, U+2660, U+2022, U+25D8, U+25CB, U+25D9, U+2642, U+2640, U+266A, U+266B, U+263C
1_ : U+25BA, U+25C4, U+2195, U+203C, U+00B6, U+00A7, U+25AC, U+21A8, U+2191, U+2193, U+2192, U+2190, U+221F, U+2194, U+25B2, U+25BC

As far as I can tell, the characters in 0x01, 0x02, 0x0E and 0x0F are missing, codepoints U+263A, U+263B, U+266B and U+263C, which are the two smiley faces, the double music note and the sun.
It would be great to have these included for full console compatibility.
