boluor opened a new pull request, #3790:
URL: https://github.com/apache/doris-website/pull/3790
## Summary
Doc page (4.x): \`scalar-functions/string-functions/replace-empty.md\` (EN).
Brings the EN page up to the level of the ZH page that already exists:
1. The EN page's first example was \`SELECT replace('hello world', 'world',
'universe');\` — that is the regular \`REPLACE\` function, not
\`REPLACE_EMPTY\`. On a page titled REPLACE_EMPTY this is confusing; the prose
never frames it as a contrast example. Removed.
2. Added two missing examples that the ZH page already has: NULL
propagation, and multi-byte (\`ṭṛìṭ\`) \`<new>\`. These are the corner cases
readers most often look up.
3. Added the missing \"if \`<old>\` is not in \`<str>\`, returns \`<str>\`
unchanged\" line to the Return Value spec, and noted the VARCHAR return type.
4. Reorganized examples as a numbered list with a one-line intro per
example, matching the ZH page's structure.
## Verification
Every SQL example was run against a single-node Apache Doris 4.1.1 cluster
using the actual mysql/mariadb client; the result blocks in this PR are the
verbatim CLI output (including the wider padding MariaDB emits on the UTF-8
row, which I matched character-for-character).
## Test plan
- [x] Run each example in the EN page on a 4.1.1 cluster — all 5 match the
result blocks exactly.
- [x] Confirm \`REPLACE_EMPTY\` behavior is unchanged; only the doc
text/examples are updated.
