ensure utf-8 encoding when processing commit message
Review Request #10520 — Created April 8, 2019 and discarded
rbt postcommand fails to post review with error
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 57: ordinal not in range(128)
When commit message has a unicode char, for example:
TlsOverhead.callOpNull true thrpt 25 12865.357 ± 135.963 ops/s
Afer localy patching the rbtool I was able to post the review into our RB server.
