Subject: [PATCH] Bytes/string encoding (#2004)
* tools: uses 'replace' error handler by default in decode()
Tools might encouter characters from non utf-8 charset (e.g. a file
name). When this happen, it's better to replace the unexpected
character by a question mark than crash the tool when all we do is
to print the string.
* tools: fix a bytes/string issue in attach_perf_event()
