HTML Rendered for bold, italic, and indent?

I am confused about the HTML that is rendeered for bold, italic, and intent. I am aware that it's changed between versions.

Is it possible to simply render <B> for bold?
Is it possible to simply render <I> for italic?

It seems that indent is also acting differently. It is rendering <P margin-left="40px"> in one environment but <P margin-left="30pt"> in another.

Is it possbile to remove the <span color too?

Generally, I can't find the documentation on how to control the HTML that is rendered.

How I'm using this editor is to allow the user to "style" a text area ... That HTML get's saved to a database & then it gets parsed & translated for another reporting tool. For example: <B> would become "\b", and </B> would become "\b0"

Now, I'm getting a whole bunch of extra stuff like <FONT> ... which I'll need to include to replace with a blank string so that the rendering page in the reproting software works correctly

PLEASE HELP ... me figure out where I can find this information at the very least. Thank you!
