# Special Character Conversions

Special characters are converted to ASCII Hex values corresponding to the special character, for example if the point or parent folder have & in the name this will translate to \_26\_ in the data stream name.  A parent folder B127Mech125&126&127 will translate to B127Mech125\_26\_126\_26\_127.  Similar substitutions will occur for:

space ! “ # $ % & ‘ ( ) \* + , - . / \_ \` ^ \~ { } | \\

This is so that the identifier can be used in URLs safely without percent encoding. 

The user can decode our changes using a by hand or automatic process to find the name of the point or subtopic that they sent in the first place.
