Use special characters in HTML Editor

Hello Community,

I’m trying to save special characters like < or > or both (like a tag) in a HTML Editor field. But SC is not considering < or similar in the field value I know that TinyMCE has methods like getContents which returns the correct strings, but SC is not using this method.
For example:

If I type:
Hello <<AA World

I would like that SC saves:

Hello & lt;& lt;AA World

However, this is saved:

Hello <<AA World

The consequence of this bug is that when SC tries to show the field again it gets confused with the << before 3.

Has anyone experienced this kind of problem?
