Windows installation errors

Sorry for my poor English, I will use translator to explain my problem. I downloaded the messages.properties file following the instructions here: How to translate the UI in any language. Then I used google translate to test translating a few lines, then I copied the translated file into

C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\openboxes\WEB-INF\grails-app\i18n

I went back to the openboxes web interface and saw that there was a change, but the lines of text I tested to translate to my language were showing errors as shown in the picture:

text2

Checking the Openboxes system settings, the endcode charset is setting at cp1252, I think it’s a mistake in the java settings but haven’t found a way to fix it.
