- * When the Internationalization API isn't enabled, we also shouldn't link
- * against ICU. However, we still want to compile this code in order to prevent
- * bit rot. The following stub implementations for ICU functions make this
- * possible. The functions using them should never be called, so they assert
- * and return error codes. Signatures adapted from ICU header files locid.h,
- * numsys.h, ucal.h, ucol.h, udat.h, udatpg.h, uenum.h, unum.h; see the ICU
- * directory for license.
