Perhaps. But the ANSI codepage does not contain all of the necessary
linedraw/box characters -- many were replaced by those "unimportant" (to
clueless Americans) accented letters. Thus, the 'OEM' codepage is very
US-centric, but can draw pretty boxes. The ANSI codepage is slightly
friendlier to an international crowd.
See http://www.cygwin.com/ml/cygwin-announce/2001/msg00014.html for more
discussion on character sets and codepage:oem.
