Betacode converter should handle lowercase input

The betacode replacer does not currently work with lowercase character, e.g. like those used in older versions of the Perseus xml files (www.perseus.tufts.edu/hopper/dltext?doc=Perseus%3Atext%3A1999.01.0125): """ta/ te a)/lla kai\ di' h(\n ai)ti/hn e)pole/mhsan a)llh/loisi."""

A solution could be to use upper() on strings that are passed in, though there needs to be some caution in handling special characters like the ‘\n’ in ‘h(\n’ in the example above.

Haven’t had a chance to test all the combinations—but this sounds reasonable. I only brought special characters up in the initial post to flag potential pitfalls with the use of slashes in betacode.

@diyclassics I’m sorry, I’m not sure I quite follow. From the documentation

This method returns a copy of the string in which all case-based characters have been uppercased.

So following this definition, \n shouldn’t be converted and is indeed treated differently. Following the same logic '\w'.upper() gives '\\W' so Replacer().beta_code(r"""pe\wn""") correctly gives 'πὲων'.
