| 32 | +If want dump complex data that will be used by non python clients you
|
|---|
| 33 | +want to use ``safe_dump=True`` as a parameter to the ``serialize()``
|
|---|
| 34 | +call. Otherwise UTF-8 strings will end up as type "!!python/unicode".
|
|---|
| 35 | +Using a large width solves problems with some parsers, too.
