I'm encountering the situation where users are choosing images that may contain brackets or curly braces (e.g., flower[1].jpg or flower{1}.jpg).  If I pass filename containing these characters directly to externalfigure, the closing bracket is mistaken for the end of the filename.

This did not work, the bracket after 1 is interpreted as the end for
externalfigure and ConTeXt looks for a figure with the name "flower[1"
but brackets in figure names could be used with \useexternalfigure.
