            Bug ID: 24926
           Summary: non-ascii characters not printing on stapbpf
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bpf
          Assignee: systemtap at sourceware dot org
          Reporter: sapatel at redhat dot com
  Target Milestone: ---

All unicode characters seem to be printing on the normal Systemtap backend =
but,
not on stapbpf, which seems to be limited to ASCII characters only.=20

This can be seen with the following scripts:=20

'probe oneshot { print("=E5=AE=98=E8=AF=9D") }'
'probe oneshot { print("=E0=A4=B8=E0=A4=82=E0=A4=B8=E0=A5=8D=E0=A4=95=E0=A5=
=83=E0=A4=A4=E0=A4=AE=E0=A5=8D") }'

After some discussion with serhei, it was noted that that stapbpf might be
assuming that a single character is a single byte.
