Cygwin does not change the encoding of file content when copying
files. Cygwin 1.7 does translate file names between the UTF-16
encoding used by Windows and the encoding you have configured in
Cygwin via the LC_ALL, LC_CTYPE or LANG variables.

Please try to desribe in more detail what you were trying to do and
how it went wrong. Also, what version of Cygwin are you using?

Line endings are a separate issue from character encodings. By
default, directories are mounted in binary mode, where file content is
left alone. Alternatively, they can be mounted in text mode, were line
endings are automatically translated between Windows and Unix style.
See for lots
more on that.
