Hello @odommo 👋
Thanks for checking out my plugin. This sounds similar to another thread – https://wordpress.org/support/topic/first-word-of-image-name-gone/
In my previous test, the results were the same with the plugin disabled as well.
Can you please provide me few examples of image filenames that you used so that I can test it out at my end. If I can reproduce it, I can try and fix it for you.
Looking forward to it.
here is the screenshot;

the name of the file was “আমাদের দেশ বাংলাদেশ.jpg”
after uploading, the file titles, alt, captions turning to … “দেশ বাংলাদেশ” (first word gone)
& this is the screenshot from: after disabling the plugin:

Default Result.
Hello @odommo
Thanks for the examples. I tried to replicate it at my end but wasn’t successful.
I have made a recording for you here – https://youtu.be/3uJ4RO0P-ZM
Please let me know if I am missing something?
If I am not wrong, then I am wondering if there is something else that is involved. Would you happen to have a staging site where you could disable other plugins and give it a try again? Just to narrow it down.
Looking forward to your feedback.
I have been reading all the threads so far that had similar issues. Few years ago, I found this – https://wordpress.org/support/topic/not-good-cyrillic-names/#post-11612241
At that time I couldn’t replicate the issue on my servers / local either. Can you please refer to that and see if that solution helps you?
Hello, I just got something.
I changed my webserver (from Litespeed to Nginx) to find out the ussue, dramatically it fixed the problem.
I think this plugin is compatible with the Nginx server on Non-English sites!
It probably has something to do with character encoding or http1 vs. http2. Nginx does not have http2 enabled by default, I think.
Just sayin’…

Sorry for the late reply.

Interesting find. I am wondering if @tavakol can relate to this.

Hello @brianbrown, thanks for chiming in. I believe this to be true and once wrote this – https://wordpress.org/support/topic/not-good-cyrillic-names/#post-11612241
Either way, WordPress by default doesn’t seem to have this issue. I will dig deeper into this and see what can be done to take care of it.
