Issue in concourse-driver-java

[NilashishC]

While running the project in Eclipse as per the tutorial given in http://wiki.cinchapi.com/display/OSS/Concourse+Developer+Setup#app-switcher I am getting an error in the Strings.java file present in the com.cinchapi.concourse.util package of concourse-driver-java.
The issue is in the replaceUnicodeConfusables(String string) method. The issue appears in this line
"case 'ʺ':" and states that "invalid character constant".
