dealing with indexation errors "json_encode error: Malformed UTF-8 characters, possibly incorrectly encoded "

I have had to force usage of `JSON_INVALID_UTF8_IGNORE `as part of `$this->jsonOptions` in order to deal with data possibly faulty data content to index.

Without this option, I was sometimes getting errors during indexation `json_encode error: Malformed UTF-8 characters, possibly incorrectly encoded
`

I did it in `algolia/algoliasearch-client-php/lib/RetryStrategy/ApiWrapper.php`, line 71 (latest PHP client 4.33)

I believe this should myabe added as a default option or made optional somewhere.

Start in algolia/algoliasearch-client-php/lib/RetryStrategy/ApiWrapper.php around line 71 and inspect how $this->jsonOptions is used during indexation. Reproduce the malformed UTF-8 json_encode failure, then verify the chosen handling prevents the reported error while preserving the intended indexing behavior.
