If anybody needs to edit font names (such as postscript name, font family name, typeface name etc) because one wants to install different subsets of the same font - there's no need to install a full fledged font editor. There's a small free java utility that does the job and is just about a megabyte in size.

Looks abandoned but works. Tested on Ubuntu font family.
