can't upload image to featured item (unicode in file name)

[pdurbin]

@g-saracca and I suspect there might be a bug in the "upload an image to a featured item" API endpoint added in #11124 and consumed by the JS code in IQSS/dataverse-client-javascript#235 and IQSS/dataverse-frontend#575.

We are unable to upload this PNG when it has the following filename:

Screenshot 2025-03-28 at 2.51.46 PM.png

This filename has a strange character between the "46" and the "PM". Namely, a narrow no-break space which is U+202F in Unicode and 0xE2 0x80 0xAF in UTF-8. Others have also noticed that macOS puts this strange character in their Screenshot filenames.

However, if we rename it to just "thinking.png", we are able to upload it.

Here's the featured item: https://beta.dataverse.org/spa/featured-item/root/46

As of this writing beta is running c4f3d76.

I chatted with @g-saracca about this bug and added the bit about "narrow no-break space" to the description above.

I also spun up the frontend locally and easily reproduced the problem (screenshots below).
