Thanks, this all looks very promising. There is so much useful information specifically about unicode that I have put it together on a separate page at: http://axiom-wiki.newsynthesis.org/UnicodeIssues?root=AxiomIssues and the original page contains a summary of this issue together with all my other 'wish-list' issues: http://axiom-wiki.newsynthesis.org/AxiomIssues?root=Axiom%20Problems I tried this: new(1, char(8721))$String and it worked immediately on my OpenSUSE 10.3 computer. I did not need export LC_CTYPE=en_US.UTF-8 or any changes to the console! I guess what I need to do is to do some experiments to see if I can read and write unicode strings to/from the console and files using various combinations of interpreter and compiled code. It would be good if you can do some of the easier things before the next release of FriCAS, then I can do some more experiments after you release it (I'm assuming the next release may not be far away?). > In principle we could provide domain(s) which would give access > to large number of special symbols via names (I am not sure if > this is really useful). Presumably (I haven't tried it yet) the compiler could read unicode characters in string literals provided that the source file is UTF-8. For inputting unicode into the interpreter via the console are there any programs already existing that could provided a virtual keyboard for special character sets? Otherwise I guess unicode characters can always be entered by their numerical value. If the symbol name are still required for the various file formats and if their designation happens to be the same, there may be some benefit in a common table?
