Dropbox not syncing files with emojis in the filename
Hello, I am trying to use dropbox to sync an application that has a bunch of image files in a subfolder. The image files are of emojis, and each filename IS the emoji that it represents. For exam...

Hi aronskaya, thanks for messaging the Community!
Some emojis are supported, however, the issue is related to UTF encoding.
The emojis that aren't working (along with many other, newer emoji) use 4 bytes, which our filesystem doesn't support. The emoji that do work on Dropbox.com are those that use less than 4 bytes.Dropbox supports using emoji that fall in the Basic Multilingual Plance in file and folder names on the website (although there are some OSes that might not sync the files to your desktop computer due to not playing nice with local filesystems).
Emoji that fall into the Supplementary Multilingual Plane won't work with the Dropbox underlying filesystem, newer emoji fall into this category and are not expected to sync with Dropbox.
Hope this helps to clarify matters!

A bit of misinformation here. Emoji are unicode characters. Unicode support in filenames *is* universal. You can name a file with emoji characters in the same way you can with Japanese or Cyrillic. I actually tested this on OS X, Windows 10 Home and Ubuntu Linux. I created a text file on OS X with an emoji filename and opened it on each platform. It's Dropbox dropping the ball here, not unicode or the OS.
Other people have also tested this: https://davidzych.com/abusing-emoji-in-windows/

8 years agoIt becomes very complicated but basically everyone is correct.
Emojis will cause a file not to sync. Some emojis are unicode and will sync without issues, others will not. Its all down to which ones fall within ASCII I believe

Are you sure you mean ASCII here? Pretty sure the number of emoji that fall within ASCII is zero

OP here. It is indeed Dropbox that is dropping the ball. Files with emoji filenames sync successfully with Google Drive, in fact that is how I solved this issue.

I hope Dropbox takes a look at the issue. Emoji seems silly, but as more users have access to input systems that include emoji more people will have files that won't sync.
That being said, I do not envy the developer that has to look into this. Unicode is a bear

I did not mean ASII, sorry, clearly that's not correct.
Basicly, BMP unicode characters is what I meant.
Apologies.
