I came across a case where a file name contained a newline (decimal 10,
0x0A) character, so that opensc-explorer broke the line when displaying it:
OpenSC [3F00]> ls
FileID Type Size
0001 iEF 0
0003 iEF 0
2F00 wEF 250
[4100] DF 0 Name: \xE8(\xBD\x08\x0F
ACOPKCS-15
The attached patch changes the print_binary function so that everything
except printable characters (including space) are displayed in hex, thus:
OpenSC [3F00]> ls
FileID Type Size
0001 iEF 64
0003 iEF 384
2F00 wEF 250
[4100] DF 0 Name: \xE8(\xBD\x08\x0F\x0AACOPKCS-15
If that seems like a sensible change, can someone commit it please?
