# file: oemCodePage.rb

require 'chilkat'

# (The CkString class is freeware)
myStr = Chilkat::CkString.new()

# A DOS console does NOT display this correctly:
print "é ô à ç\n"

# What we need is the OEM (DOS) code page...
# OEM code pages are listed here:
# http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/unicode_81rn.asp
myStr.appendAnsi("é ô à ç\n")

# Emit the string in the character encoding of your choice:
# ibm850 is the OEM code page for Latin1
print myStr.getEnc("ibm850")
