Thanks. It works. I added user environment variable "PERL_RL" with value "o=0" to my computer. Both dbish and CPAN shell look clean now.

I think that's because the Perl terminal is trying to use ornaments
(you're seen ANSI escapes which are used to change the color and
brightness of the text and to control the terminal). But cmd.exe does
not provide an ANSI terminal.
As DBI::Shell uses Term::ReadLine, I think you can disable that by
defining an environment variable PERL_RL with the value
> set PERL_RL= o=0
as explained here:
http://search.cpan.org/perldoc?Term::ReadLine#ENVIRONMENT
Maybe there is a more reasonable way to do it by adding some lines to
the configuration file of DBI::Shell, but that should at least work.
