I am afraid a serious error has been introduced into textext in the last update(s).

This used to work in metapost for typesetting text with a %-sign:

label(textext("66\%"), origin);

Now the % somewhere ends a line prematurely because the job aborts with: ! mpx file ended unexpectedly.

Can Hans please repair this, suddenly a lot of my typesetting is broken.

Verified. Thanks for analizing this, I was wondering where those ! mpx file ended unexpectedly. messages came from in a document Mojca sent me. Taco
