Hello,
OK, thanks for reaction.
One more example - \text instead of ascii mode:
----
\starttext
\type{%@$}
A\footnote{\type{*\$%
}}
B\footnote{\type{*\$\%
}}
\stoptext
----
gives:
"
*\$
*\$\%
"
in the footnote.
IOW, I cannot simply print "%": "%" at the end yields "" whilst "\%"
produces "\%".
Is there a simple way to prinst simple "%"?
(There is probably a more clumsy way - type \letterpercent instead of %
- but this is a minimal sample; in my real sample there are many "%"s to
be shown as "%".)
Why not just use asciimode?
To understand why \footnote{\type{...}}} doesn't work, you need to
understand TeX's "digestive system". \type{...} (and asciimode) work by
modifying the catcode tables. However, they are are used inside a
footnote, the argument of \footnote is parsed according to the catcode
table which is active when footnote is passed. Under the default catcode
table, % is a comment, so when you type:
\footnote{\type{*\$%
}}
the argument of \footnote is `\type{*\$}`
So, if you want \footnote to "see" the %, you need to activate a catcode
table where % is a letter. So, the simplest solution is to use \asciimode.
