- * are quick-checked for FCD.
- *
- * - UNORM_INPUT_IS_FCD
- * Set if the caller knows that both s1 and s2 fulfill the FCD conditions.
- * If not set, the function will quickCheck for FCD
- * and normalize if necessary.

- * - U_COMPARE_CODE_POINT_ORDER
- * Set to choose code point order instead of code unit order
- * (see u_strCompare for details).
- *
- * - U_COMPARE_IGNORE_CASE
- * Set to compare strings case-insensitively using case folding,
