Sooooo... the whole point of adding bdf2subf into #p9p was to get acme to display the Terminus font properly :3
Research has shown that using any other font is :unacceptable:
However, since the last time I used #acme it looks like that there has been lots of changes to #plan9port in relation to font display. The current favoured way seems to be running fontsrv that exposes most of the system's fonts to p9p via 9pfuse and that is also able to do on-demand conversion of these fonts to #Plan9's subfont format. But somehow it really does not look good here with the latest Terminus TTF. Sadly X11 PCF fonts are not supported by fontsrv either. There is a subfont Terminus conversion floating around but it was not quite correct either. Thankfully, running bdf2subf on the latest BDF version of Terminus fixed everything.
For those who want the conversion I use and instructions on how to make theirs: https://git.bleu255.com/plan9port/file/font/terminus/README.html
