This error occurs since conversions between character encodings may change the length of the data.

However, if the SQL data type is varchar(n) or char(n), the application binds the parameter as SQL_C_CHAR for the C type, and SQL_CHAR or SQL_VARCHAR for the SQL type, and the character encoding of the client is UTF-8, you may get a "String data, right truncation" error from the driver even if the value of ColumnSize is aligned with the size of the data type on the server. The ColumnSize parameter of SQLBindParameter refers to the number of characters in the SQL type, while BufferLength is the number of bytes in the application's buffer.

The driver manager won't attempt this conversion when calling the SQLWCHAR versions of the ODBC API (for example, SQLDriverConnectW). The driver manager attempts this conversion when calling the SQLCHAR versions of the ODBC API (for example, SQLDriverConnectA). Currently, data corruption occurs when one or more characters in the string aren't valid UTF-8 characters. If the client encoding is UTF-8, the driver manager doesn't always correctly convert from UTF-8 to UTF-16. For more information, see End-User-Defined and Private Use Area Characters. Each library may produce different results when performing these conversions. Conversions in the driver use the Windows, Linux, or macOS conversion libraries.

Conversions performed on the server within Transact-SQL use the Windows conversion library. Windows, Linux, and macOS convert characters from the Private Use Area (PUA) or End User-Defined Characters (EUDC) differently. For more information, see musl libc - functional differences from glibc. For example, en_US.UTF-8 isn't available.
