+// There is an issue in the Unicode CLDR database (v36):
+//
+// - Polish has 4 different plural types: "one", "few", "many", "other"
+// - However, some units, say "short/digital-kilobyte", only have "other" defined
+// - When we localize 1024 (number) into kilobytes, it use the "one" type
+// - Since "short/digital-kilobyte/one" is not defined in the database, `globalize` throw exception
+//
+// In all of our supported languages, we also observed the same issue in Portuguese as well.
+//
+// As a hotfix, we are patching the Unicode CLDR database for all `[long/short/narrow]/digital-*` rules to make sure it include all plurals needed for that language.
+//
+// For a long term fix, we should move forward to a newer version of CLDR database, which is outlined in https://github.com/rxaviers/cldr-data-npm/issues/78.
