Previously String#% was overridden on versions after Ruby 1.9 to match the 1.8 behavior where missing keys in the expanded format are ignored and not replaced. This is likely suprising behavior in modern Ruby. This removes the previous patch, but still allows overriding this behavior optionally by calling
FastGettext.allow_invalid_keys!
.This is less surprising behavior, but still allows a migration path for people who rely on the current missing key behavior. Let me know if this seems reasonable! Thanks!
