“There are many broken links”

I have this plugin installed on a client’s website (in Farsi language) and it has notified us of many broken links.

When I checked the last 20 supposedly-broken links from the settings, I found that some are, in fact, false positives. This seems to be due to the plugin not correctly decoding URL strings containing non-Latin characters. For example, the following URL is flagged as broken:

/wp-content/uploads/2022/03/%C3%98%C2%B3%C3%98%C2%B1%C3%99%C2%85%C3%98%C2%A7%C3%9B%C2%8C%C3%98%C2%B4%C3%9B%C2%8C.png

and is displayed on browser as follows:

However, when decoded, this URL is valid:
/wp-content/uploads/2022/03/سرمایشی.png

So it seems that the plugin is not handling URL encoding/decoding properly for non-Latin characters, resulting in “many broken links” notification from the plugin.

Could you please look into this issue? thanks in advance.
