FCC API: addressing unexpected error

[Ofnuts]

Bingo!:

Trying this (this is your data above):

http://data.fcc.gov/api/block/find?format=json&latitude=32.35204448&longitude= -106.77485461&showall=true

Gives:

Output:
{"Block":{"FIPS":"350130001041007"},"County":{"FIPS":"35013","name":"Doña Ana"},"State":{"FIPS":"35","code":"NM","name":"New Mexico"},"status":"OK","executionTime":"1004"}

With the ñ conveniently in columns 72.
Looking at the JSON standard, Unicode characters are accepted, and the response seems to be proper UTF-8, so it would be your code that doesn't handle UTF-8 properly (assumes ASCII only?).
