Trying to recreate the weird smart quote conversion.

Edit: oh, it's fine.... maybe it's a kbin issue?

For context, in the original post, this was the result:

http://www.gcmap.com/mapui?P=5%EF%BF%BD2%26%238242%3B51.59%26%238243%3BN+9%EF%BF%BD7%26%238242%3B23.26%26%238243%3BW+-+28%EF%BF%BD17%26%238242%3B7.68%26%238243%3BN+121%EF%BF%BD38%26%238242%3B17.31%26%238243%3BE%0D%0A&MS=bm&DU=mi

Note that single-quotes %27 became %26%238242%3B which encodes ′ which is an HTML entity for U+2032 ′, i.e. smart quotes but broken all the way to hell and back.
