I am seeing some other issues with `\read` as well. For example, `\def\first{hello world}` (notice the two
spaces) will store 11 tokens "hello␣world" in `\first` but storing `hello world` in a text file
named `example.txt` and reading that file with `\newread\example \openin\example=example.txt \read\example
to\second` in LuaMetaTeX stores 13 tokens "hello␣␣world\n" in `\second`. LuaTeX and other TeX
engines would store just 12 tokens "hello␣world\n". This is less of an issue than the one described
in the original post and can likely be fixed by using `\scantokens` on `\second`.
On my machine from this:
\starttext
\newread\example
\openin\example=example.txt
\read\example to\hello
\read\example to\world
\closein\example
(\meaningfull\hello)
(\meaningfull\world)
[\hello\ \world]
\stoptext
I now get:
(global macro:{hello})
(global macro:world)
[hello world]
For
{%
hello}
world
But I used a patched version of \read that is not yet uploaded.
