How can I extract this fancy VGA font?

I have access to an old
Toshiba 386 PC (T2000Sx) with an extremely unusual VGA system font; which I would like to recover as a font file and document in a web site.
How can I write a program which reads the font data from VGA memory and writes it to the floppy?

The system barely boots from floppy, has little memory (1MB base + 9MB extension) and no hard drive. It used to boot Debian 2.1 via a ZIP drive on the parallel port, but that does not seem to work any more.
The question is a combination of:
1. are there (DOS) programs to do this already? (I have not found any yet; but maybe there are?)
2. programming tools: which language/compiler can I use? Obviously this machine won't run any modern OS, so GCC / VS is out of the question. I had some experience 20 years ago with writing .COM executables manually from assembly, but it is rusty; are there any better programming tools nowadays?
3. VGA standard: at which address in the address space can I find the font data, and how many bytes should I read? I have not found this yet in other sources online.
