System settings can affect how gadget text is rendered

Issue Summary

Currently JVM inherits file and system encoding from the operating system, unless JVM parameters are specified

Usually this is not a problem as the operating system is configured for UTF-8, however, a slight can cause this problem.

Environment

Any operating system not using UTF-8 for file or system encoding

Steps to Reproduce

1. Configure OS to use Latin-1 encoding (or ISO-8859-1 or Windows-1252) instead of UTF-8
2. Use a multi-byte character such as è (e-Grave, U+00E8)

Expected Results

Character renders as è

Actual Results

Character renders as Ã, ¨

Notes

We should ship the UTF-8 settings by default because there is no good reason to inherit the file/system encodings from the operating system.

Workaround

Add the following JVM parameters:

-Dfile.encoding=utf-8
-Dsun.jnu.encoding=UTF-8
