On Scala version 2.11.7, when compiling Scala code on Mac OS X or Linux systems, garbled text may occur if Chinese characters appear.

The solution is as follows: edit the following two execution scripts respectively:

$ vim `which scala` 

$ vim `which scalac`

Find:

[ -n "$JAVA_OPTS" ] || JAVA_OPTS="-Xmx256M -Xms32M"

Replace it with:

[ -n "$JAVA_OPTS" ] || JAVA_OPTS="-Xmx256M -Xms32M -Dfile.encoding=UTF-8"

Recompile the script, and Chinese will then display correctly.
