Ensuring UTF-8 Encoding in PHP's json_encode Output for Non-ASCII Characters

Despite efforts to enable UTF-8 encoding through mb_internal_encoding and utf8_encode, json_encode continues to return Unicode-escaped characters in the resulting JSON string. This issue can be addressed through various approaches.

JSON_UNESCAPED_UNICODE Option in PHP 5.4

If using PHP 5.4 or later, leverage the JSON_UNESCAPED_UNICODE option when invoking json_encode. This option explicitly disables Unicode escaping, leading to the expected output: {"a":"á"}.

Custom JSON Encoder with Non-ASCII Support

For earlier PHP versions, create a custom JSON encoder that does not escape non-ASCII characters. This approach ensures that the JSON string accurately represents the original input.

Pear's JSON Encoder Modification

An alternative solution involves modifying Pear's JSON encoder by removing lines 349 to 433. This change effectively disables Unicode escaping within the encoder, resulting in the desired output.

Conclusion

These techniques provide viable ways to output UTF-8 encoded JSON strings, enabling accurate representation of non-ASCII characters without Unicode escaping.
