Convert Intellij native-to-ascii properties file to Eclipse variant

Intellij creates Uppercase unicode Escape characters and eclipse likes to create them in lowercase.
This results in problems with Versioning System.

Simple sed script to convert these from intellij to eclipse variant ->

sed "s/\(\\\\u....\)/\L\1/g" messages.properties  -i 

.... Or just set the correct parameter in idea.properties ->

idea.native2ascii.lowercase=true
