[API-users] funny characters in common names / vernaculars for species

Hi both,

the JSON specification defaults to UTF8, thats why you often do not see that encoding being specified in http again:
https://en.wikipedia.org/wiki/JSON#Data_portability_issues <https://en.wikipedia.org/wiki/JSON#Data_portability_issues>


Still as you have spotted this is not correct UTF8 as you can see on our portal page:
http://api.gbif.org/v1/species/2882753/vernacularNames <http://api.gbif.org/v1/species/2882753/vernacularNames>

The species is from our backbone which claims it is taken from the GRIN dataset, where you can see the same problem:
http://www.gbif.org/species/101354008 <http://www.gbif.org/species/101354008>
http://www.gbif.org/species/101354008/vernaculars <http://www.gbif.org/species/101354008/vernaculars>

Also in the verbatim data as it came in:
http://www.gbif.org/species/101354008/verbatim <http://www.gbif.org/species/101354008/verbatim>


Ill try to see how that ended up there.
Markus
