+<para><FirstTerm>codepage:[ansi|oem]</FirstTerm> - Windows console 
+applications can use different character sets (codepages) for drawing
+characters.  The first setting, called "ansi", is the default.
+This character set contains various forms of latin characters used
+in European languages.  The name originates from the ANSI Latin1
+(ISO 8859-1) standard, used in Windows 1.0, though the character
+sets have since diverged from any standard.  The second setting
+selects an older, DOS-based character set, containing various line
+drawing and special characters.  It is called "oem" since it was
+originally encoded in the firmware of IBM PCs by original
+equipment manufacturers (OEMs).  If you find that some characters 
+(especially non-US or 'graphical' ones) do not display correctly in 
+Cygwin, you can use this option to select an appropriate codepage.
