Some characters like "ü" where being represented as
["u", "̈"]
in ruby < 2.3.0 and it caused errors down the line.I tried using
String#unicode_normalize
but turns out it's only available since ruby 2.2.0, so I'm using ActiveSupport normalization.I don't know how this kinds of workarounds need to be documented? In the future if CocoaPods moves to ruby >= 2.3.0 this normalization wouldn't be needed anymore.
Fixes #5294
