linhongliu-db opened a new pull request, #37651:
URL: https://github.com/apache/spark/pull/37651
### What changes were proposed in this pull request?
This PR proposes to support ASCII value conversion for Latin-1 Supplement
characters.
### Why are the changes needed?
`ascii()` should be the inverse of `chr()`. But for latin-1 char, we get
incorrect ascii value. For example:
```sql
select ascii('§') -- output: -62, expect: 167
select chr(167) -- output: '§'
```
### Does this PR introduce _any_ user-facing change?
Yes, fixes the incorrect ASCII conversion for Latin-1 Supplement characters
### How was this patch tested?
UT
