LaTeX and \l and generated pdf and suppressing chars

[Norbert Preining]

Hi Ulrike,

thanks for your answer.

I cannot disagree ;-) Having the small / in 0x20 is a great place ;-)

Ok.

But I do NOT get a space on copy/paste!!! If there were a space, it
would copy/paste:
	W lodzimierz
but it doesn't.

So I guess the glyphtounicode.tex or something else is actually ignoring
the space.

Or ignoring glyphs with missing mapping?

Actually I do NOT want a space, the above looks strange, right!?

I don't get a space in copy/paste.
I only get a space when using pdfminer text extraction.

This is my question: How did the space disappear from pdf copy/paste?
You said:

but this is not what I see.

I am not talking about *my* LaTeX documents, but about arXiv's
submissions, and there are LOTS and people do ALL kind of strange
things, trust me.

And we have to live with it.

Best regards, and thanks a lot
