Is there the word "妡" in the national standard lexicon? When naming my daughter, the police station said that this word cannot be used.

Although this character is a relatively uncommon Chinese character, it should still be usable.

This character is listed in the national standard GB 18030-2005 Information Technology Chinese Coded Character Set and is within the scope of mandatory provisions. The picture below is a screenshot of the full page of the GB 18030-2005 standard that contains this word.
