// formatRange() returns the same output as format() when the date-time difference between
// the start and end date is too small.
// Test case when skeleton can't be retrieved from resolved pattern (bug 1298794).
// - Best-fit pattern for the skeleton "MMMMMdd" is "M月dd日".
// - Best-fit pattern for the skeleton "Mdd" is "M/dd".
//
// So in both cases the skeleton characters in the pattern are "Mdd", which means we can't
// retrieve the original input skeleton by simply inspecting the resolved pattern.
//
// Also see: https://unicode-org.atlassian.net/browse/ICU-13518
