fask_sqlalchemy "When it comes to text, it is completely based on Unicode." Therefore, fask_sqlalchemy can use Chinese as the index condition, if the Chinese text is based on Unicode. In terms of consistency and completeness of data processing, it is desirable to use Unicode-based Chinese text as the index condition. As for the efficiency of data processing, there is no conclusion without practical operation, but if you are doing text keyword extraction index, using Unicode Chinese as the Primary Key or Index is necessary for the consistency and integrity of data processing, and I guess efficiency It will be faster than going around in circles without using Unicode Text.
