gPXE will depend on support from the underlying system to provide
support.  With a typical x86-compatible BIOS in text mode, you're
limited to the current "OEM code page" (
http://en.wikipedia.org/wiki/Code_page#IBM_PC_.28OEM.29_code_pages ).
I believe uEFI (the successor to the BIOS boot) can provide unicode
support.  Most gPXE builds depend on a typical BIOS.  I believe there
is at least some work on EFI/uEFI builds (which I'm sure someone else
here could comment on)

What are you looking to do?  Use the "echo" command within a script to
print out something for an end user to see perhaps?  Anything after
gPXE boots to something else (ie Linux kernel, an NBP (Network Boot
Program) like PXELINUX, SAN disk) will depend on that target as gPXE
will no longer have control.
