I have to display a long writer document with inserted control characters (ascii code < &H20)
Is there any way to highlight these characters with colors or with placeholders?
Both in the options and on the net I have not found anything
Thanks in advance for any suggestion
LO 7.4.4.2 snap, Ubuntu 16.04 ,writer saved as odt
edit: I know how to enter characters with CTRL+SHIFT+U+hex code+Enter
I am only interested in having the possibility of highlighting those already present in the document, due to batch insertion tests that I had done in the past, as they are not visible (each occupy one byte in the text, I can see them from the macro, in search I find them but I cannot see them at sight)
In an editor I see this placeholder (a square icon with two zeros in the first row and a 0-1 in the second ), in writer I don’t see this placeholder.
Is there any way to see it at these characters? It would be enough for me to be able to see this placeholder or something similar
I do not want them to be effective, I do not want i.e. have the same effect as in a terminal.
I do not want to display them with their names.
I want only to display with a placeholder or with a color on request
But I don’t see anything relevant in the options
Apparently it seems not, but before insisting on trying I would like to ask for confirmation
