Paul,

Thanks for confirming.

In the actual document I had originally entered the inline equation using
Insert -> Math -> Inline. This morning I deleted that yellow box and used
ERT to enter the string. Error committed.

Now, in the actual document I had to re-enter the ERT several times to get
it to compile. It may be that when entering the ERT content I tended to type
], backspace to delete, then type \. Perhaps correcting the typo was the
cause.

I'll see with the display version if it's my fingers mis-typing a backslash
that creates the unprintable character.

Carpe weekend,
