Encoding problem when building

Hi Kelly
   I investigated how local specific characters get into generated 
sources in corba module.  Those classes are generated by following 
command idlj
c:/openjdk/dep/jdk1.7.0_02/bin/idlj -J-XX:-PrintVMOptions 
-J-XX:+UnlockDiagnosticVMOptions -J-XX:-LogVMOutput -J-Xmx512m 
-J-Xms512m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -td 
"c:/openjdk/ojdk8_ojdk_739/../ojdk8_ojdk_739-debug/corba/gensrc" -i 
"../../../../src/share/classes/org/omg/PortableServer" -i 
"../../../../src/share/classes/org/omg/PortableInterceptor" -corba 3.0 
-fall -pkgPrefix PortableServer org.omg 

   I checked idlj help but there is no encoding specific option. My 
locale environment vars are listed below

$ locale

   Could you give me any hint about how to force idlj to generate ascii 
chars only?

Best regards,

The issue is that in module corba and jdk, some java classes are generated by program.  They happen to contain Chinese characters in comment.  However, they are compiled with explicit option "-encoding ascii" in makefile.  This results in unrecognizable chars complained by javac (Error: encoding ascii unmappable chars) .  I have a patch that removes all unnecessary "-encoding ascii" but I am not sure all its side effect.  Shall I submit a bug?
