> regexp_instr and regexp_replace treat string positions as UTF-16 code units

> Key: SPARK-57932
> URL: https://issues.apache.org/jira/browse/SPARK-57932
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Eric Yang
> Priority: Major
> Labels: pull-request-available
>
> *The issue:*
> Spark string positions are 1-based code points (instr, locate, position,
> substring, length). For strings containing supplementary characters (code
> points > U+FFFF, e.g. emojis), these two functions gave wrong results:
> - regexp_instr('😀ab', 'ab') returned 3 instead of 2.
> - regexp_replace('😀aXa', 'a', 'Z', 3) returned 😀ZXZ instead of 😀aXZ (replaced
> a match before position); regexp_replace('😀😀', '😀', 'Z', 3) returned 😀Z
> instead of the input unchanged. This is the sibling of the LIKE fix in
> SPARK-55453.
