+ * Reason for Obsolete:
+ * This portion of code converts special characters or '\' to string,
+ * so when those characters are in object or attribute name, h5ls display
+ * as visible characters.
+ * However if a user come up with object or attribute name with special
+ * character in programming, this code takes away control over '\'
+ * (escape character) from the user and causes confusion for the output,
+ * also it’s not possible to handle all the cases in this way.
+ * This also causes discrepancy from how the string data saved in

+ * Also other HDF tools don’t convert characters like this, so this
+ * causes inconsistent output among tools.
