Johnathan Kew also wrote me 3 weeks ago this about sfnt2woff:

"
By way of a small warning, I should perhaps note that the code
you're using has not been touched (or even looked at) in a -long- time,
so I'm not completely confident that the woff files it creates are
necessarily 100% conformant with the final version of the woff spec.
Although I am not aware of any specific incompatibilities, this may be
something to bear in mind if you do encounter any problems using files
created by that tool.
