parens in author strings

[cmcooney]

Parentheses in the author strings causing problems. Cf these three urls:

Chokes with parens:
http://pantagruel.ci.uchicago.edu/philologic4/Aozora/query?frequency_field=&script=&end=0&format=json&author=%E7%B4%A0%E6%9C%A8+%E3%81%97%E3%81%A5+%28Shiraki+Shizu%29&q=%E6%88%80%E4%BA%BA+%E3%81%AE+%E5%91%BC%E5%90%B8+%E3%81%A8&start=1&report=concordance&arg=&date=&title=&philo_type=&method=proxy

Doesn't choke with parens removed:
http://pantagruel.ci.uchicago.edu/philologic4/Aozora/query?frequency_field=&script=&end=0&format=json&author=%E7%B4%A0%E6%9C%A8+%E3%81%97%E3%81%A5+Shiraki+Shizu&q=%E6%88%80%E4%BA%BA+%E3%81%AE+%E5%91%BC%E5%90%B8+%E3%81%A8&start=1&report=concordance&arg=&date=&title=&philo_type=&method=proxy

Doesn't choke again:
http://pantagruel.ci.uchicago.edu/philologic4/Aozora/query?frequency_field=&script=&end=0&format=json&author=%E7%B4%A0%E6%9C%A8+%E3%81%97%E3%81%A5&q=%E6%88%80%E4%BA%BA+%E3%81%AE+%E5%91%BC%E5%90%B8+%E3%81%A8&start=1&report=concordance&arg=&date=&title=&philo_type=&method=proxy

Surrounding that full author name with quotes generates a result:

http://pantagruel.ci.uchicago.edu/philologic4/Aozora/query?frequency_field=&script=&end=0&format=json&author=%22%E7%B4%A0%E6%9C%A8+%E3%81%97%E3%81%A5+%28Shiraki+Shizu%29%22&q=%E6%88%80%E4%BA%BA+%E3%81%AE+%E5%91%BC%E5%90%B8+%E3%81%A8&start=1&report=concordance&arg=&date=&title=&philo_type=&method=proxy

However, searches with parentheses in titles generate results just fine without quotes:

http://pantagruel.ci.uchicago.edu/philologic4/Aozora/query?frequency_field=&script=&end=0&format=json&author=&q=%E6%88%80%E4%BA%BA+%E3%81%AE&start=1&report=concordance&arg=&date=&title=%E5%B9%B8%E7%A6%8F%E3%81%B8%E3%81%AE%E9%81%93+%28%E3%81%93%E3%81%86%E3%81%B5%E3%81%8F%E3%81%B8%E3%81%AE%E3%81%BF%E3%81%A1%29&philo_type=&method=proxy

A not-so-foolish consistency would be nice with this, unless there was a good reason for disallowing parens in author strings. Then again, if there is a better way to group original names + name transliterations than I did, I'm happy to consider it.
