javadoc "unmappable character" errors #2813
Description
./gradlew assemble generates a number of error messages during the javadoc task which are all similar to the following:
MPAndroidChart/MPChartLib/src/main/java/com/github/mikephil/charting/data/filter/Approximator.java:11: error: unmappable character for encoding ASCII
* http://en.wikipedia.org/wiki/Ramer???Douglas???Peucker_algorithm
This is a common problem. The fix is to set the charset to utf8 in the javadoc task.
