Just noticed your ascii requirement. Looked it up and found this:
"Plain text files normally use one of two types of character sets: ASCII or
ANSI. DOS uses ASCII (pronounced "ask-key"). ANSI ("an-see") is the character
set used by Windows. There are many variations and sub-sets but ASCII and
ANSI are virtually identical until you start using some extended characters
such as äèö. Sometimes the term ASCII file is used to describe any plain text
file."
Since Windows uses ANSI for text, I do not know how you would get the column
into ASCII within Windows. Sorry.
