<text> and <data> arguments are parsed by parse_criteria function (it uses shlex and optparse for parsing). Data that is passed to parse_criteria function is extracted from "line" argument of do_<…> methods. This "line" argument is read from self.stdin by cmd.Cmd and passed to do_ methods. In Python 2.x sys.stdin (which is default for cmd.Cmd.stdin) is binary, so "line" is a bytestring; its encoding is self.stdin.encoding. That's why <text> and <data> argument values was previously bytestrings; when passed to other scrapely functions they eventually got implicitly decoded using sys.getdefaultencoding() - this usually leads to UnicodeDecodeError if input text is non-ascii. The fix is to decode these arguments using self.stdin.encoding before passing them to scrapely. This is done after shlex call because shlex doesn't support unicode. Non-ascii "field" arguments are still unsupported.
