I have two questions regarding the mergeFonts tools:
1. According to this page, mergeFonts can "Merge multiple fonts, add/remove glyphs, and change glyph names". However, I am unable to figure out how to use the tool to remove a glyph from a file. Is it really possible with the mergeFonts tool? If yes, how?
2. It seems that replacing a glyph with the mergeFonts tool will not update the parameters (like FontBBox) of the final ps file. Is it correct? If yes, is it possible to update the corresponding entry using the AFDKO tool?
