So... keep it simple, set

and use vi or something else that comes with cygwin to create the file

The first 127 characters of UTF-8 are identical to the
first 127 characters of ASCII, and latin1 and iso-8859-1.
If you don't use any characters that need accents or special symbols,
then nothing will be encoded in UTF-8, because its only
the characters OVER the first 127
(see chart @ http://www.babelstone.co.uk/Unicode/babelmap.html).
I'm still trying to figure utf-8 out, but it seems to me that 0x0 -
0xff is part of the utf-8 encoding. This chart makes things clearer
... at least for me :)

The proposed UCS transformation format encodes UCS values in the range
[0,0x7fffffff] using multibyte characters of lengths 1, 2, 3, 4, and 5
bytes. For all encodings of more than one byte, the initial byte
determines the number of bytes used and the high-order bit in each byte
is set.
An easy way to remember this transformation format is to note that the
number of high-order 1's in the first byte is the same as the number of
subsequent bytes in the multibyte character:
Bits Hex Min Hex Max Byte Sequence in Binary
1 7 00000000 0000007f 0zzzzzzz
2 13 00000080 0000207f 10zzzzzz 1yyyyyyy
3 19 00002080 0008207f 110zzzzz 1yyyyyyy 1xxxxxxx
4 25 00082080 0208207f 1110zzzz 1yyyyyyy 1xxxxxxx 1wwwwwww
5 31 02082080 7fffffff 11110zzz 1yyyyyyy 1xxxxxxx 1wwwwwww 1vvvvvvv
This encoding scheme is wrong; where did you get it from? Maybe it's the
obsolete UTF-8...
