Learn more about bidirectional Unicode characters
Here we add support for the following two ESQL functions: * LTRIM: remove leading spaces from a string * RTRIM: remove trailing spaces from a string We also fix an issue with the handling of unicode white spaces. We make use of unicode code points to identify unicode whitespace characters instead of relying on ASCII codes. Moreover, iterating bytes in a Unicode string needs to consider that some Unicode characters are encoded using multiple bytes.

This is work originally done by @salvatore-campagna against the original ESQL repo. He didn't get to merge it before he stepped out for a while so I've modernized it and will land it here. |
