Hello,
so far, I considered the unicode symbol \u00a0 should be converted to
the tilde in TeX. But now I've got a counterexample:
\documentclass{article}
\begin{document}
test:\newline
aaa~aaa\newline
~~~~~aaa~~~aaa\newline
\end{document}
The use of "~" as non-collapsing white-space does work inside lines,
but does not work at the beginning of lines. "~~~~~" is ignored. I
think I know why (kern after break?), but it does not help me to
realize:
How to represent the symbol \u00a0 in TeX?
Thanks for the suggestions.

In article
<5f54bce3-9dc1-4ea8...@m19g2000yqh.googlegroups.com>,
Howdy,
White space at the start of a line is thrown out by TeX. place an empty
box at the start of a line (\mbox{}), so
\documentclass{article}
\begin{document}
test:\newline
aaa~aaa\newline
\mbox{}~~~~~aaa~~~aaa\newline
\end{document}
works.
by the way, if you are trying to align items this is WRONG way to do it.
Use the tabbing environment or make a tabular.
Good Luck,
Herb Schulz

~ is not "non collapsing space": it does what is the duty of spaces

in TeX, that is, disappearing after a line break.
I would never use a sequence of spaces in that way, but rather
\hspace or \hspace* that allows for precise control.
If you really want to use U+00A0 in that way,
\usepackage{newunicodechar}
\newunicodechar{^^^^00a0}{\leavevmode~}

perhaps written by somebody else, then TeX should typeset it
as intended.

does \leavevmode). You probably meant
\newunicodechar{^^^^00a0}{\mbox{}~}
or
\newunicodechar{^^^^00a0}{\leavevmode\vadjust{}~}

Do these commands also work in math mode?

Actually, I don't know what \newunicodechar does with the definition,

so it might be math-incompatible.
And they don't work well in math mode -- they allow line breaks.
I suggest instead that the non-breaking space be defined as
\newunicodechar{^^^^00a0}{\leavevmode\nobreak\vadjust{}~}

the equivalent of
\protected\def<char>{...}
Notice that <char> can be used in the body of the definition,
because it's already been tokenized. One can so "safely" say
\newunicodechar{<char>}{\ifmmode...\else...\fi}
if <char> is intended to be used in math mode with a different
meaning than in text mode.

Many kinds of 'something' are really not suitable for conversion to formats

question is HTML and similar markups, which makes extensive usage of
(U+00A0) not only to avoid line beaks at specific points but also
to emulate indentation.
And I assume that HTML is certainly suitable for conversion to formats
at level higher than dvi or pdf.

The use of U+00A0 to 'emulate indentation' is abuse of HTML -- to the
