[Unexpected] Auto change text

[babman92]

Hi every body,

I have simple rule

**After I scan my project, I got some results: **

I ran

mvn org.walkmod.maven.plugins:walkmod-maven-plugin:apply -Dch
ains=pmd -Dproperties="D:/{project_name}/src/main/resources/rulesets/custom-rul
esets.xml"

and got results:

Above rule is fixed but many my comment in Vietnamese and Japanese has been changed to unicode string. I really don't want that.

Anybody can help me fix this?, thanks so much.
