I had the same issue. Having rummaged in the library, I found that, when using the --quiet flag, apparently, wkhtmltopdf passes the same thing to the stder as to the stdout, that is, a byte string with a picture. However, in the library, the stder stream is decoded to utf-8, which causes the error.
Until the bug is fixed, it can be bypassed as follows:

try:
  jpeg = imgkit.from_string(html_string, False, options={'quiet': ''})
except UnicodeDecodeError as err:
  jpeg = err.args[1]
