As far as the keyboard driver is concerned, there is no limit, but 
RISC OS is usually configured to work in an 8-bit text encoding 
environment and practically everyone has the system set to Latin-1, so 
you are limited to using the standard Latin-1 characters, which 
luckily do include Þ and ð and a few others, but may not include all 
of the characters you would wish to have in your new reformed spelling 
theme. If so, then you are stuck as far as RISC OS is concerned. In 
principle RISC OS systems can be switched to Unicode completely, but 
in practice this would not be wise because few applications would cope 
with that.

Producing a new keyboard driver is a pretty technical task because the 
tools we have for the job are programmers' tools and not end-user 
tools. There is software to produce keyboard drivers (!IKHG), but I am 
not sure whether it is still available and in any case, it expects to 
be used in conjunction with the developer tools because it generates 
code that is then assembled into a RISC OS keyboard driver module. If 
you can build RISC OS itself from its sources you will probably manage 
to build a new keyboard driver, too.

The generated keyboard driver can produce any character for any 
combination of Shift, Alt and the ordinary keys, and you can even have 
sequences of keys produce different characters, e.g., on a German 
keyboard, you press ´ (a so-called "dead key") followed by a and you 
get á, the same key followed by o produces ó etc.
