I was trying to upload a file in a support chat to my online bank. The upload process was failing. The file size limit is 2 MB, my file is 312 KB. The support agent said that I should restart my device and/or try a new internet connection. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤦‍♂️" title="Man facepalming" aria-label="Emoji: Man facepalming">.

I knew it wasn& #39;t my internet nor device because I had already switched from the mobile app to the web app https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤷🏼‍♂️" title="Man shrugging (medium light skin tone)" aria-label="Emoji: Man shrugging (medium light skin tone)">.

I decided to put my debugging hat on. I checked the file name: `wohnungsgeberbestätigung.pdf`. I replaced the `ä` with a normal `a` and bam it worked. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🎉" title="Party popper" aria-label="Emoji: Party popper">.

I guess I applied the experience from one user story that I worked on where some versions of Android threw exceptions because the file names didn& #39;t contain & #39;valid characters& #39;.

It& #39;s weird that it happened for them on web too. They need to update their upload logic.
