Russian symbols are incorrectly gets from properties file through the i18nHelper in my Jira plugin.

[Arthur Foss]

Hello, I have a problem with getting the Cyrillic characters.

This is my property file:

#put any key/value pairs here
duedate.job.cron=0 10 20 ? * MON-FRI
text.rus=тест текст

This is the Java code that gets the property:

final I18nHelper i18nHelper2 = ComponentAccessor.getI18nHelperFactory().getInstance(Locale.getDefault());
final String property = i18nHelper2.getText("text.rus");

libraries that I use

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.util.I18nHelper;
import java.util.Locale;  

Here is a screenshot of what jira getting in debug:

The workaround is to replace the text with Unicode characters:

text.rus=\u041D\u0435\u043A\u043E\u043D\u0441 \u0438\u0441\u0442\u0435\u043D\u0442

 But this does not completely suit me.

Property file encoding is utf-8.

jira version 7.4

I found this guide about internationalization.: https://developer.atlassian.com/server/framework/atlassian-sdk/internationalising-your-plugin/

It says - "Please Note: If you any of your translations use non-ASCII characters, which will include most languages other than English, then you must convert your text file to a Unicode-encoded ASCII text file using a tool such as native2ascii."

For this reason, all non-English characters are must be replaced by their Unicode. 

After all, java and utf-8 can support the Cyrillic, but in jira it is not possible(( Can someone explain why? At what level does this limit appear?
