In particular, the problem is in the implementation of the text editor, which assumes (in `string-snip%', specifically) that the height and descent of text is determined only by the font --- and that's not true if a glyph is substituted from some other font. We'll fix this, but probably not right away. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
