### Search before asking

### Version
master
### What's Wrong?
In FE, when constant folding rule is applied, '汇总' is always less than '2022-01-01'.
But when I send a sorting sql which runs a sorting in BE, the result is contrary.

FE should keep the same logic as BE.

be中，字符串的比较是基于utf8的编码，按字节比较，字节是基于uint8
fe中，java基于signed byte
导致be中fe中，编码值对应的数字值不同导致排序不同
