First, how new fonts can appear in document:

1) Applying fonts using UI

2) Pasting RTF or RVF (RichView format) from Clipboard

3) Inserting RTF or RVF from file

4) Drag&Drop RTF or RVF (may be from another application)

As for (1), it's your work to prevent undesirable fonts.

If you want strictly restrict formatting, it's simple.

Define all allowed formatting in TRVStyle.TextStyles, right click the

editor, choose "Settings" in the context menu, select "Use a predefined set

of styles".

After that, no new formatting will be used when inserting RTF or RVF. Fonts

from inserted documents will be mapped to the most similar existing

formatting.

This affects (2), (3) and (4)

If you want to restrict font names.

Insert document in hidden TRichView linked with its own TRVStyle component,

then iterate TextStyles of this RVStyle and correct their FontName

properties.

Then use SaveRVFToStream and InsertRVFFromStreamEd to insert data in the

main document.

It will work with (2) (use OnPaste event) and (3).

It's not possible with (3), you'll need to exclude RVF and RTF from

AcceptDragDropFormats property.
