16% experimental stripping
17
18%D For a while we had stripping of special chars built into the analyzer
19%D but Khaled suggested to generalize this so I changed the code into a
20%D manipulator there.

23%D \definefontfeature[default][default][mode=node,formatters=strip]
24%D \stoptyping
25%D
26%D However, in \MKIV\ it makes more sense to also provide it as a more
27%D general feature. Here we implement this as experiment. I might
28%D cook up a few more variants in both variants.
