+ * @brief
+ * Modifies a string in place, removing leading and trailing whitespace characters.
+ * Optionally, it can remove other characters or ranges in addition to whitespace.
+ *
+ * @param input - a reference to a Glib::ustring which will be modified in place.
+ * @param also_remove - optional range of characters to remove in addition to whitespace.
+ *                      NOTE: these characters are inserted into a regex range (square brackets) and
+ *                            therefore may need to be regex-escaped. It is the responsibility of
+ *                            the user to pass a string that will work correctly in a regex range.
