### Question

This SQL can be executed successfully, but the following warning will appear in the com.clickhouse.jdbc.parser.ClickHouseSqlParser class.
```

### Expected Behaviour

### Code Example

```java
public void insertDataIntoCH(String chUrl,
String table,
String tenantId,
List columns,
String csvData,
boolean chAsync,
Integer size) {
try {
String sql = buildClickHouseInsertSql(chUrl, table, columns, chAsync);
boolean asyncEnabled = !GrayManager.notUseAsyncInsert(chUrl) && chAsync;
{
JdbcConnection dst = jdbcService.getBiCHConnection(tenantId);
String fullSql = sql + "\n" + csvData;
dst.executeUpdate(fullSql);
}
log.info("success insert ClickHouse: ch:{},table:{},nums:{}", chUrl, table, size);
} catch (SQLException e) {
log.error("error insert", e);
throw new RuntimeException("ClickHouse insert error", e);
}
}

```

### Configuration

#### Environment
* [x] Cloud
* Client version:
* Language version: jdk21
* OS: linux

#### ClickHouse Server
* ClickHouse Server version: 25.8.13.73
* ClickHouse Server non-default settings, if any:
* `CREATE TABLE` statements for tables involved:
* Sample data for all these tables, use [clickhouse-obfuscator](https://github.com/ClickHouse/ClickHouse/blob/master/programs/obfuscator/Obfuscator.cpp#L42-L80) if necessary

Start by reproducing the INSERT statement with Chinese CSV data and inspect com.clickhouse.jdbc.parser.ClickHouseSqlParser, where the lexical warning is reported. Trace how the SQL is parsed before execution and add or update coverage for this input. Done means the valid insert still executes without emitting the lexical error warning.
