MariaDB Error 1638: Non-ASCII Separator Limitations
Description
This error indicates that a SQL statement or function is attempting to use a non-ASCII character (e.g., accented letters, symbols) as a separator or delimiter. MariaDB's current implementation for certain string functions or parsing operations may not fully support these multi-byte characters, leading to unexpected behavior or this explicit warning.
Error Message
Non-ASCII separator arguments are not fully supported
Known Causes
3 known causesUsing Non-ASCII Delimiters in String Functions
Employing characters outside the standard ASCII range (e.g., '€', 'é', '✓') as separators in functions like `SUBSTRING_INDEX` or `FIND_IN_SET`.
Inconsistent Character Set Configuration
A mismatch between the client connection, database, or table character sets can lead to misinterpretation of multi-byte characters used as separators.
Legacy Function Behavior
Some older or specific MariaDB string manipulation functions might have inherent limitations in handling multi-byte characters as separators, even with proper UTF-8 settings.
