I'll see what I can up with to load fonts by request with the tools supplied within a vanilla pharo image and a given URL (don't nail me on that, I'm known not to keep promises). I guess if I will contribute code I will have to give a signature and mail it, right!?

One "quicker-written-than-thought" posting: GNU Smalltalk implements from-source bootstrapping (the image gets constructed from a source kernel if not available). GNU Smalltalk can do this (I don't know the deep internals) since the compiler is implemented i C/ native. Squeak itself was "bootstrapped" once or twice (depending on the point of view, SystemTracer did transform the image into something different). Pharo, as I understand (CMIIW) was bootstrapped by reimplement, delete previous version, distribute. Naiad (is, will be) bootstrapped by keeping a minimal ObjectMemory-Invocation image connected by a Compiler-having image. So... as long there's no SLang-convertable compiler, squeak and siblings won't be able to be a "from-scratch-implementation" built from the sources, right? And there will be always a big graph of objects that are "created, saved, non-recreatable"? Hm, 'scuse me, I'm wearing my troll-mask today ;-)

Of course I see my ugly mistake. I will create a dummy package in that case.

Fonts once removed in vanilla squeak are a PITA to load back and re-anchor in the system-wide font collections... So basically, I'd like to vote for "remove and make loadable steph by steph"
