[webkit] [9] Review request for 8158926: Char value is set as integer, not as character

[Arunprasad Rajkumar]

Hello Kevin, Guru, Murali,

Please review the following fix.
JIRA: https://bugs.openjdk.java.net/browse/JDK-8158926

Webrev: http://cr.openjdk.java.net/~arajkumar/8158926/webrev.00

Issue: Java Char type is converted to JS integer type, which is not correct.

Solution: Since there is no char type present in JS, convert it to JS 
String type.

Regards,
Arun
