v2.1.0

This release adds support for UTF-8 delimiters in patterns.  The
following example using U+2014 EM DASH as a delimiter is now valid:

    x—/some/file/path—

Error messages about invalid operators now also render properly when
UTF-8 input is provided.  Given the pattern ‘ä/re/’, the following used
to be displayed:

    grab: Invalid operator ‘

This has been corrected in this release to:

    grab: Invalid operator ‘ä’
