Invalid character

[ncordon]

From bblfsh logs we got the following messages:

rpc error: code = Internal desc = invalid character '{' looking for beginning of object key string
rpc error: code = Internal desc = invalid character '{' after object key
rpc error: code = Internal desc = invalid character '}' after object key
rpc error: code = Internal desc = invalid character '{' after array element
rpc error: code = Internal desc = invalid character 'd' after object key

Probably unhandled driver crash. It may be caused by the native driver dumping crash info to stdout.

Or maybe an invalid escaping while encoding UAST in the native driver? This would explain { specifically.
