Is it an uncommon word? This is used for naming. I'm afraid I can't settle down in the future, such as ID card and bank card. So ask the great gods.

Although "Zhu" does not belong to the general standard Chinese characters, it belongs to the character set. At present, most computer operating systems use the character set, so it can be displayed. Any input method that encodes all Chinese characters (more than 20,000 words) in the GBK character set can be input, such as "multi-Chinese character and graphic symbol input method". To be on the safe side, you'd better consult with the registration center before making a decision.
