When I try to download a JSON file, all UTF-8 characters are converted to unicode (e.g. Commander des cr\u00e9dits). I would like to preserve UTF-8 and accentuated characters during export.
Accentuated characters are escaped because of the nature of JSON formats. Most of JSON decoding logic accepts both escaped and non-escaped text to obtain the same result. Therefore OneSky outputs the escaped version to avoid potential problems (e.g. unicode encoding issues) for some languages and frameworks.
There is no harm in using the escaped characters in the JSON file.
