[Python-es] Problemas de encoding json utf-8

Jue Mar 21 00:17:14 CET 2013

Esto, ya es json valido tal cual.

x = JSON.parse('{"groups": {"1": {"fields": {"1": {"widget_type":
"DropDownList", "options": {"00005": {"text": "Si"}, "00006": {"text":
"No"}}, "name": "\u00bfHoy Trajiste a Clase tu XO?", "dependence":
"00001"}, "0": {"widget_type": "DropDownList", "options": {"00004":
{"text": "No"}, "00003": {"text": "Si"}}, "name": "\u00bfRecibiste en
Alg\u00fan Momento tu XO?", "dependence": "00001"}, "2": {"widget_type":
"DropDownList", "options": {"00007": {"text": "Totalmente Sana"}, "00009":
{"text": "No Funciona"}, "00008": {"text": "Parcialmente Sana"}}, "name":
"\u00bfC\u00faal es el Estado Actual de tu XO?", "dependence": "00001"}},
"name": "Datos de XO"}, "0": {"fields": {"0": {"widget_type":
"RadioButton", "options": {"00001": {"text": "Si"}, "00002": {"text":
"No"}}, "name": "\u00bfEl Alumno se Encuentra en Clase?", "dependence":
""}}, "name": "Asistencia"}, "3": {"fields": {"0": {"widget_type":
"TextInput", "options": {"00017": {"text": ""}}, "name": "Comentarios",
"dependence": "00001"}}, "name": "Comentarios"}, "2": {"fields": {"0":
{"widget_type": "MultipleCheckBox", "options": {"00023": {"text": "Jugar
con el Robot"}, "00020": {"text": "Programar"}, "00025": {"text": "Pegarle
a mi hermano"}, "00024": {"text": "Jugar al Ping Pong"}, "00021": {"text":
"Editar mi Blog"}, "00016": {"text": "Grabar videos"}, "00022": {"text":
"Dibujar"}, "00014": {"text": "Escuchar M\u00fasica"}, "00015": {"text":
"Ver Videos"}, "00012": {"text": "Estudiar"}, "00013": {"text": "Leer"},
"00010": {"text": "Facebook"}, "00011": {"text": "Juegos"}, "00026":
{"text": "Jugar con el perro"}, "00027": {"text": "Para Nada"}, "00018":
{"text": "Sacar Fotos"}, "00019": {"text": "Chatear"}}, "name": "\u00bfPara
qu\u00e9 Utilizas tu XO?", "dependence": "00001"}}, "name": "Uso de la
XO"}}}')
Object {groups: Object}

No se de donde habrás sacado este supuesto diccionario, pero eso es ya json
valido, es decir no necesitas volverlo a serializar.
Y eso es muy facilmente detectable, si tefijas, "\u00bfHoy Trajiste a Clase
tu XO?" esta cadena tiene el primer caracter unicode ya codificado para que
javascript pueda interpretarlo bien.

Ademas vemos que es una cadena unicode, pero no lleva la u delante, lo que
me hace pensar que ya fue serializada una vez o es un diccionario de
python3.

Antes de plantearse intentar serializarla una vez mas y luego al
desserializar obtener resultados extraños, me plantearia mirar de donde
obtienes esos datos y como. Porque te repito, es muy extraño que ese
diccionario por si solo tenga cadenas unicode sin la u delante y usando
python2.
