[9] RFR: 8161937: non-ASCII characters in source code comments

[Naoto Sato]

Hello,

Please review this small fix for the following issue:

https://bugs.openjdk.java.net/browse/JDK-8161937

The proposed fix is located at:

http://cr.openjdk.java.net/~naoto/8161937/webrev.00/

This is just to replace those non-ASCII characters used in comments with 
the equivalents in ASCII range. It's hard to tell the difference from 
the webrev above, but the change replaced the following characters:

U+2014 (EM DASH) -> U+002D (HYPHEN-MINUS -)
U+2019 (RIGHT SINGLE QUOTATION MARK) -> U+0027 (APOSTROPHE ')
U+201C (LEFT DOUBLE QUOTATION MARK) -> U+0022 (QUOTATION MARK ")
U+201D (RIGHT DOUBLE QUOTATION MARK) -> U+0022 (QUOTATION MARK ")
