+ * Stripping diacritics and natively comparing the strings is much faster than using localeCompare.
+ * localeCompare also fails to search partials, it only searches the full string match, so is quite
+ * useless for a filter box. 
+ * 
+ * This method sacrifices some of the benefits of localeCompare, such as κόσμε == kosme and instead
+ * focuses solely on diacritics, which should be fine for the general use case. 
+ * 
+ * @param str the full string to search against (for this panel, it's always the Data Source #name)
+ * @param sub the filter string to search with
