Queries containing ’ don't work correctly

[gaurav]

Compare https://name-resolution-sri.renci.org/lookup?string=HODGKIN%E2%80%99S%20DISEASE&autocomplete=false&highlighting=false&offset=0&limit=10 with https://name-resolution-sri.renci.org/lookup?string=HODGKIN%27S%20DISEASE&autocomplete=false&highlighting=false&offset=0&limit=10

This is the Windows smart quote; presumably the same problem will show up for smart double-quote. I should be able to replace this on queries so that users won't notice this issue.

We should also test the quote characters from Unicode.
