I just found out that what I previously reported as a problem with the
TeXmacs interface also occurs
in "plain" FriCAS:
$ fricas
Checking for foreign routines
FRICAS="/usr/local/lib/fricas/target/amd64-portbld-freebsd12.1"
spad-lib="/usr/local/lib/fricas/target/amd64-portbld-freebsd12.1/lib/libspad.so"
foreign routines found
openServer result 0

Type:
Void
(2) ->f(α))
Line 1: f(α)
.A.BC
Error A: Missing mate.
Error B: syntax error at top level
Error B: Possibly missing a )
Error C: The character #\PLUS-MINUS_SIGN is not an FriCAS character.
4 error(s) parsing
Note that the double right parentheses on line (2) are not a typing error
by me, but are somehow
echoed back by the system itself when I type 'f(α)'.
