test case for Encoding.Default.

This a test case for Encoding.Default.
It shows CodePage, WebName and EncodingName property.

How to use:
1. If your 'locale -a' doesn't show ja_JP.utf8, add Japanese locale support to
your environment. 
2. Run encoding.exe on Japanese locale with wine,
   i.e. LANG=ja_JP.UTF-8 wine encoding.exe

Expected behavior:
   Shows 932, shift_jis, 日本語 (シフト JIS)
   This means the default encoding is code page 932.

Actual behavior:
   Shows 65001, utf-8, Unicode (UTF-8)
   This means the default encoding is code page 65001.
