Antoine Stevan 01d8961eb7 use to_lowercase in str downcase (#10850) ... # Description as we can see in the [documentation of `str.to_lowercase`](https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase), not only ASCII symbols have lower and upper variants. - `str upcase` uses the correct method to convert the string 7ac5a01e2f/crates/nu-command/src/strings/str_/case/upcase.rs (L93) - `str downcase` incorrectly converts only ASCII characters 7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124) this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in `str downcase`. # User-Facing Changes - upcase still works fine ```nushell ~ l> "ὀδυσσεύς" | str upcase ὈΔΥΣΣΕΎΣ ``` - downcase now works 👉 before ```nushell ~ l> "ὈΔΥΣΣΕΎΣ" | str downcase ὈΔΥΣΣΕΎΣ ``` 👉 after ```nushell ~ l> "ὈΔΥΣΣΕΎΣ" | str downcase ὀδυσσεύς ``` # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - ⚫ `toolkit test` - ⚫ `toolkit test stdlib` adds two tests - `non_ascii_upcase` - `non_ascii_downcase` # After Submitting		2023-10-27 19:16:17 +02:00
