boluor opened a new pull request, #3837:
URL: https://github.com/apache/doris-website/pull/3837
## Summary
Two small en/zh sync fixes in string functions:
- **`rtrim.md` (en)**: backport the LENGTH-based example from ZH that
demonstrates `RTRIM` only strips ASCII space by default (not `\t` or `\n`).
Useful corner case the EN page was missing. Re-numbered the rest of the
examples (3..8 → 4..9) to keep them in order.
- **`strleft.md` (zh)**: remove redundant example 9 (`utf-8 字符串`). Example 7
already demonstrates UTF-8 multi-byte behavior with more realistic input;
example 9 was a single shorter case that added no new info and was the only
structural diff vs EN.
## Verification
`SELECT LENGTH('hello world \t\n '), LENGTH(RTRIM('hello world \t\n '));`
on Doris 4.1.1 returns `(16, 15)`, matching the documented expected output.
## Scope note
The broader bidirectional sync across the rest of the P1 "both-extra" bucket
(`trim`, `field`, `substring`, `strright`, `array-count`) requires substantial
content-level translation work and is deferred — those pages' example sets
diverged in non-trivial ways and need per-example review rather than mechanical
alignment.
