Bug Description

I'm a developer who works in an organization that uses JFrog's Artifactory as its repo system.
I couldn't figure out why Composer was complaining that your nette/schema and later nette/utils libraries weren't in the repository when I could plainly see them. However, I noticed that they were missing a lot of listings on their "properties" tab in Artifactory. And this tipped me off. When I saw the emoticons in the Description fields, I removed them and repackaged the .zip. I then uploaded them to Artifactory and suddenly Composer could see them.

Steps To Reproduce

... If possible a minimal demo of the problem ...

Expected Behavior

... A clear and concise description of what you expected to happen.

Possible Solution

  Remove emoticons from your composer.json for your packages.  Keep everything UTF-8.

Shouldn't you rather report this as a bug in JFrog's Artifactory? The composer.json file is, of course, entirely in UTF-8.
