Missing special characters in Leaflet popup

I’m trying to display the proper name of cities with special characters in spanish such as ’tilde’ Á, however I’m getting false encoding in the popup layers as you can see in the image:

I have my html charset defined as <meta charset="utf-8" /> and the .geojson is also alright:

{"type":"Feature","geometry":{
"type":"Point","coordinates":[-74.1059716,4.650528403]},
"properties":{
"DPTO_CCDGO":11.000000,
"MPIO_CCDGO":1.000000,
"CPOB_CNMBR":"BOGOTÁ D.C.",
"CPOB_NANO":2011.000000,
(...)

Any idea on how to fix it?
I already checked with Chrome 58 and Firefox 53 with same result.
