When using TRANSLATE_CHK to verify UNICODE normalization form translations, any valid Unicode string can be translated to any of the normalization forms. A successful result (0) is expected unless the compatibility ideographs U+FA6C, U+FACF, U+FAD0, U+FAD1, U+FAD5, U+FAD6, or U+FAD7 are present, because these characters normalize outside the BMP, that is, outside the range U+10000 to U+10FFF.
For all normalization forms, these characters normalize as follows:
| Ideograph | Normalized Form |
|---|---|
| U+FA6C | U+242EE |
| U+FACF, | U+2284A |
| U+FAD0 | U+22844 |
| U+FAD1 | U+233D5 |
| U+FAD5 | U+25249 |
| U+FAD6 | U+25CD0 |
| U+FAD7 | U+27ED3 |
