Special character in bundle descriptor

[ChrisVeigl]

Special characters in the bundle descriptor (e.g. german Umlaute in string constants for property default values) are not correctly transferred to the ACS via "Download Component Collection".

The reason might be a wrong character encoding of the .xml file or during the processing/transfer.

also consider XML special characters e.g. <> " / They should automatically be quoted.

all locations that open/store files on the ARE now use the respective methods from class ResourceRegistry:

Method to get the contents of a file encoded in UTF8 or UTF8 with BOM https://github.com/asterics/AsTeRICS/blob/master/ARE/middleware/src/main/java/eu/asterics/mw/services/ResourceRegistry.java#L607

method to store a resource encoded in UTF8 https://github.com/asterics/AsTeRICS/blob/master/ARE/middleware/src/main/java/eu/asterics/mw/services/ResourceRegistry.java#L640

The implementations use the library apache-commons-io and the class BOMInputStream to correctly deal with UTF8 with and without BOM http://www.rgagnon.com/javadetails/java-handle-utf8-file-with-bom.html https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/input/BOMInputStream.html

@TODO:

• The WebACS handles special characters correctly.

• The C# ACS does not correctly handle special characters when calling "Download Component Collection" and a bundle_descriptor contains e.g. öäüß.

• Additionally the C# ACS adds the text encoding=UTF-16 to the xml string, when uploading a model or when calling storeModel.
