In reply to Kavya.

@Miguel - yes, that was it. I'll look at that plugin, but...

@Kavya - while I take your point (and it's the way WordPress is going, plugins for everything), it's a reduction in functionality from what we had before.

"If you're an occasional users of accented characters, where would you look for them?" is the question I would ask here. I don't know the Windows 10 keystrokes. I know there's a Character Map accessory somewhere, but most of the people I know wouldn't know about it (although they use PCs daily).

And, even knowing that I can use the Classic Block for accented characters, I still have to create a whole new block - I can't convert/transform my Paragraph Block by using the option in the top-left corner.

I'm not against Gutenberg - I typed a whole post using it last week, instead of copying and pasting from Word - but WordPress as a whole becomes less useful if it requires specialist knowledge to use the way you want it to. I think so, anyway ;-)
