UnicodeDecodeError on gdb.execute

For some special file I need to look at the source code from within the
GDB extension.

I did this with the reasonable and obious
output = gdb.execute("list *" + hex(sal.pc), False, True)
(and get more lines with a follow-up "list" [not all are needed,
otherwise the gdb.parameter("listsize") could be adjusted).

I _think_ the problem I expect now is because of a system with Python3
which has default utf8 encoding, but it _may_ was also in before:
There's a python exception UnicodeDecodeError in this line whenever it
contains "extended" ascii.

"list" in GDB shows the code correctly; also
(gdb) py gdb.execute("list 14")
shows the correct text, but as soon as python has to internally decode
it to store a string:
(gdb) py gdb.execute("list 14", False, True)
Traceback (most recent call last):
File "<string>", line 1, in <module>
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfc in
position 18: invalid start byte
Error while executing Python code.

is there any way I could adjust the encoding used for storing
gdb.execute as string?
Is there a reason that this isn't by default set to match
gdb.target_charset() ?

Thanks for insights to this issue, too,
Simon
