Title: LPS- 52225 - Export is not working for web-content structures in case non-ASCII characters are used for field names

this issue is caused by illegal image path,for example the path will be like
:8ball: group/11943/com.liferay.portlet.journal.model.JournalArticle/12029/_Изображение1677_0_ru_RU

Fix Reason:
:8ball: 1:the method "getModelPath" can be used like:
public static String getModelPath(StagedModel stagedModel) {
return getModelPath(stagedModel, null);
}

:8ball: 2:there are some other places use like this :
search by keyword "*StagedModelDataHandler.java".
