Possible issue with escaped URLs in sitemap?

[yokoyama-flogics]

Hi,

Thank you for providing this great script. I'm currently using it, and I came across a potential issue. When I include URLs in the sitemap that are percent-encoded (e.g., https://flogics.com/wp/2016/01/raspberry-pi-%e3%81%a7%e5%8b%95%e3%81%8f%e3%80%81%e3%83%87%e3%83%bc%e3%82%bf%e3%83%99%e3%83%bc%e3%82%b9%e9%80%a3%e6%90%ba%e3%83%90%e3%83%bc%e3%82%b3%e3%83%bc%e3%83%89%e3%82%b9%e3%82%ad%e3%83%a3/), I receive the following error:

Indexing already requested previously. It may take a few days for Google to process it.

I've waited several days, but the error persists. However, according to Google Search Console, it appears that the URL is being crawled and indexed correctly.

I'm not sure if this is expected behavior or if it's a limitation of the Google Indexing API. Should URLs in the sitemap be decoded before submitting them? Or is there any other explanation for this issue?

I appreciate your insights and assistance in clarifying whether this might be a bug or if there's something I'm missing.

Thanks in advance for your help!
