`  === General problem with naming conventions for WP page address links ===  In ``http://en.wikipedia.org/wiki/Progressive_retinal_atrophy``, the link to ``Siamese`` is embedded as ``http://en.wikipedia.org/wiki/Siamese_%28cat%29``, When this link is copy-pasted into a Mac Mail new email, for example, the link is converted by Mail to ``http://en.wikipedia.org/wiki/Siamese_%2528cat%2529``, which is invalid (Mail replaced the percent character with its hex equivalent). Please advise your editors to avoid using special characters, or, at least, to avoid using ``escape`` codes, in links and anywhere else that copy-paste could result in such a conversion. For this case, the solution is simple: the name of the page shoud be ``http://en.wikipedia.org/wiki/Siamese_cat``. The linking page ``...Progressive_retinal_atrophy``, as coded, violates ``http://en.wikipedia.org/wiki/Wikipedia:How_to_edit_a_page#Links_and_URLs`` in the paragraph which begins, ``In the URL, all symbols must be among: ...``, and the paragraph which follows.`
