Description fred.wang 2010-02-06 12:16:38 UTC 
mathml_test/arrows_thick.xml
mathml_test/arrows_verythin.xml

I've recently noticed that most arrows of the two tests above are no longer displayed. Worse, when saving the file and reloading it, an error "invalid characters" is displayed.

This stretchy arrows use a thot shape. In displaybox.c::DisplaySymbol, the value pBox->BxAbstractBox->AbShape seems to be incorrectly set, so an empty rectangle is displayed. I guess that for the same reason, they are also not well exported by document/translation.c
