Getting mathematical fonts on Linux
There may be mathematical truetype fonts already on your system
or available through you packaging system.
I searched the internet for them.
points to a STIX Fonts Project beta font download
download and extract these fonts they are *.otf they can
be converted to *.ttf as described here:
the ttf fonts can be installed in Linux and installed in the
fallback directory (which may need to be created)
I tried the raw *.otf and it did not work so the conversion
to ttf may well be necessary.
I copied to /usr/share/fonts/truetype
Then I did
xset fp rehash
and could use the fonts but they may have been already installed.
Testcase (supplied by customer):
create table test ( testcol VARCHAR2(10));
insert into test values (unistr('\D835\DCAB'));
then view the table in SQLDeveloper.
Please comment if you have any problem/improvements.
