I tried to paste ‎21629  [CJK Unified Ideographs Extension B]. It previewed ok, but stripped all content after the character upon posting.

    I've tried to paste it in as well. Using IE and Edge on Windows 10. Not working either. Could be a font fallback issue or that range is not supported here?

    Testing on Safari and Chrome on OS X doesn’t seem to work either.

    Is this the same issue as using-emoji-cuts-my-post-off? I found it odd that I could preview, but not post.

    Yes @Katy Mawhood - BMP is uXXXX . Anything with 5 letters like 21629 (I think you mean u21629) is non-BMP. That basically mean most recent large unicode additions like cjk extension b or emoji as the BMP is essentially filled up a while ago. Only the odd one or two standalone characters can be added in BMP, not whole blocks of new stuff.

    Assuming the database in question is MySQL, this looks like the MySQL utf8 vs utf8mb4 encoding issue.

    Not necessarily - I fixed a bug in the Linux kernel a few years ago about nls file naming of non-ascii file names, and the Linux kernel does not use mysql :smile:

    Unicode 2.0(?) is BMP only - so it is perfectly legitimate for anything to claim to be 'unicode compliant' and yet does not support non-BMP characters.
