Embed code is not saved when emojis exist

Hi,

Thanks for your greate plugin, it really helps to solve the embed problem for the social medias for classic editor user. There is only one thing which I hope can be improved in the future. When there are emojis in the embed code, they can’t be saved in the custom field, I have to manually remove the emojis then only it can be saved. Sample codes as below:

<blockquote class="tiktok-embed" cite="https://www.tiktok.com/@shuibsepahtu/video/7120892464201764122" data-video-id="7120892464201764122" style="max-width: 605px;min-width: 325px;" > <section> <a target="_blank" title="@shuibsepahtu" href="https://www.tiktok.com/@shuibsepahtu">@shuibsepahtu</a> Siakap sawah ???? <a title="pershuibofhappyness" target="_blank" href="https://www.tiktok.com/tag/pershuibofhappyness">#pershuibofhappyness</a> <a title="fyp" target="_blank" href="https://www.tiktok.com/tag/fyp">#Fyp</a> <a title="belut" target="_blank" href="https://www.tiktok.com/tag/belut">#Belut</a> <a target="_blank" title="? original sound - Shuib Sepahtu" href="https://www.tiktok.com/music/original-sound-Shuib-Sepahtu-7120892499144559386">? original sound - Shuib Sepahtu</a> </section> </blockquote> <script async src="https://www.tiktok.com/embed.js"></script>

Any method to solve this limitation?

Thanks.
