Feel free to create a SetString method inside ActivityUserData that takes a
StringPiece16 and converts it to UTF8 internally.

Done.

Shouldn't these be x86 and x64, given that the defined symbols are CPU
architectures and not strictly Windows architectures?

[manzagop (departed), 2016/12/06 21:39:03]

Yeah... These are the "platform" strings that the crash frontend expects from
windows clients. In fact, the above way of getting the product name/version/etc
is also windows specific.

[bcwhite, 2016/12/06 22:37:32]

Acknowledged.
