Undocumented change to non-HTML escaped strings

[RichardoC]

Can this behaviour please be documented and warned of in the main readme and function comments?

Current users might be relying on the sanitised return values and wouldn't be expecting this to change in a patch version.

Thanks!

You are right. After further consideration I change the behavior back to the previous and added the flag DisableEscapeHTML to provide users the option.
