ESQL: LTRIM, RTRIM and fix unicode whitespace (#98590) 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. 2023-08-17 23:30:12 +08:00			`[[esql-ltrim]]`
