I am confused because the code implies that it's a normal string.

In GDBRemoteCommunicationClient::FindProcesses:
```
      if (match_info.GetProcessInfo().GetArchitecture().IsValid()) {
        const ArchSpec &match_arch =
            match_info.GetProcessInfo().GetArchitecture();
        const llvm::Triple &triple = match_arch.GetTriple();
        packet.PutCString("triple:");
        packet.PutCString(triple.getTriple());
        packet.PutChar(';');
      }
```
The server also thinks it's a normal string:
```
      } else if (key == "triple") {
        match_info.GetProcessInfo().GetArchitecture() =
            HostInfo::GetAugmentedArchSpec(value);
      } else {
```
However, I do see it hex encoded in the logs when I get a **response**:
```
lldb             <  17> send packet: $qfProcessInfo#42
lldb             < 219> read packet: $pid:1427;ppid:1;uid:24900;gid:24900;euid:24900;egid:24900;name:2f75

riple:616172636836342d2d6c696e75782d676e75;#ea
```

To be sending a triple to the server I think I need to use:
```
(lldb) platform process list --arch arm64
error: invalid combination of options for the given command
```
But it doesn't actually work.
