[5/8] mesos git commit: Fixed `Version::validateIdentifier()` for Unicode edge case.

[ne...@apache.org]

Fixed `Version::validateIdentifier()` for Unicode edge case.

The test case `u8"1.0.0-b\u00e9ta"` in `VersionTest.ParseInvalid` caused
an abort in `isctype.cpp` with VS 2017. Changing the `char` to an
`unsigned char` prevents this.
