emojis in look data text fields breaks run_look

[jlthomps]

It's possible this is actually a RJSONIO issue, so I apologize if it is not relevant here. I'm experiencing a failure of the run_look function when there are emojis in a text field returned by my look. It renders in the look, but I have to remove the offending row before run_look will work. I figured this out via trial and error, but the error given by R is:
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In grep("^[[:space:]]*[[{]", content) :
input string 1 is invalid in this locale

@jlthomps thanks for this report, we'll have to ensure that we handle unicode appropriately. I think this would be a simple fix (check encoding, escape appropriately, return data) but the R SDK is getting some work that might render this change obsolete so I'm not sure if this will make it into the package in its current form. If the changes seem to be getting pushed out further then I will push a quickfix
