Problems with unicode to utf8 characters

[dknx01]

I tried to convert a shp file into geojson with uniscode characters inside. Some seems to be converted to UTF-8, if I use Shapefile::OPTION_DBF_CONVERT_TO_UTF8 option, but not All. Especially german Umlaute seems to be not converted.

ö is still \u00f6

This is not a matter of reading and converting UTF-8 from the shapefile DBF, which is happening, but rather a deliberate choice for the GeoJSON output, where multibyte unicode characters get escaped.

I could add an option to Geometry::toGeoJSON() in order to output unescaped multibyte UTF-8 characters, basically it's just a matter of passing JSON_UNESCAPED_UNICODE flag to PHP json_encode function. I will think about possible issues with that and eventually add it.

By the way, currently escaped JSON is 100% valid and should be the in the most interoperable form though, why is it causing you issues?

The issue is that I cannot use the current output directly. So I need another step to handle them.

An option would be a good choice. Maybe the same for other options for json_encode, so that everyone can pass them through.
