Cannot repro...  Logfile is created correctly and commands and their output are logged there.  The file encoding for the logfile is utf-8.
A couple of things though:    1.  changing \ to / does not guarantee a valid Cygwin path.    2.  the cd does nothing because bash -l starts the shell in the home directory.    3.  Once you've started bash, you don't have to supply the full path so "/bin/bash.exe" and "/bin/tee.exe" are fine (assuming your path and mounts are set correctly)
Are any files on a remote share?Are any of the paths relative?Do any of the paths have spaces in them?
You should check out the cygpath utility...
