https://en.wikipedia.org/wiki/Latin-1_Supplement_(Unicode_block) (0x80-0xff)
I know, i18n is not going to happen in Serenity itself, so this might not seem like a problem - but especially the browser is likely going to have to display letters not used in the English language sooner or later, so it's probably unwise to put random symbols in reserved unicode ranges.

I wonder what these symbols are for?
Those symbols were just me playing around with FontEditor while creating the fonts :)
Hi,
I work on this subject. As a first step, i extend font format to support Latin Extended A (from 256 to 384 characters). For now, FontEditor and Browser HTMLParser support is done.

That looks great @asliturk!
