Description

@jenkins-infra-bot
jenkins-infra-bot
opened on Jun 6, 2014

Version: 1.564

How to reproduce:

  • Create a view, and start it with an emoji in the name
  • Enjoy the 404 page

I'm fairly sure this will impact other locations as well, but I haven't verified.

Possible solutions:

  • Do not allow characters in names that will create this behaviour
  • Make sure that url generated can be used to find the view

      I can reproduce in Jenkins 2.32.3 with all sorts of items: view, freestyle job, folder.  I created items called "X robofolder" etc., where "X" is a robot face (U+1F916).  JIRA throws a 500 error and doesn't accept this comment if I use the actual emoji character…
      


      The items do get created, and displayed on the home page, but the emoji character is stripped from the URL, so clicking through results in a 404.
      


      It seems to happen as soon as you go >= U+10000 (which has a 4-byte rather than 3-byte UTF-8 representation). That character does not work in an item name, but U+FE6B does.
      


      The character can be anywhere in the name — it doesn't have to be at the start, it will be stripped out regardless.

      I'm unable to reproduce this on 2.176.2. I created a job with the snowman emoji in the name and it worked fine. I was able to edit the configuration and everything.

      Updates to Unicode support in Java likely fixed this bug since Jenkins has required Java 8 for a while now. The initial ticket is using Java 7.

    It actually looks like there are still issues here. Snowman works (https://emojipedia.org/snowman/), but "ugaritic letter thanna" does not (https://www.compart.com/en/unicode/U+10398)

      I was about to say that it was a newer emoji, but it appears as though it's not new at all. Strange.
      


      I know that we use XML 1.1 instead of 1.0 in order to allow for better Unicode support, though that's likely irrelevant here unless you're trying to use an emoji in an XML tag name.
