Any way to return PHP `json_encode` with encode UTF-8 and not Unicode? [duplicate]

Solution 1:

{"a":"\u00e1"} and {"a":"á"} are different ways to write the same JSON document; The JSON decoder will decode the unicode escape.

In php 5.4+, php's json_encode does have the JSON_UNESCAPED_UNICODE option for plain output. On older php versions, you can roll out your own JSON encoder that does not encode non-ASCII characters, or use Pear's JSON encoder and remove line 349 to 433.

Solution 2:

I resolved my problem doing this:

• The .php file is encoded to ANSI. In this file is the function to create the .json file.
• I use json_encode($array, JSON_UNESCAPED_UNICODE) to encode the data;

The result is a .json file encoded to ANSI as UTF-8.

Solution 3:

This function found here, works fine for me

function jsonRemoveUnicodeSequences($struct) {
   return preg_replace("/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($struct));
}

Solution 4:

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.
