The varchar type of the tdengine database is displayed incorrectly

### Description

The varchar type column in the tdengine database displays Chinese characters normally in tdengine explorer, but displays as a hex string in dbeaver.

### DBeaver Version

DbEaver Community Edition 25.1.2.202507061449

### Operating System

Windows 11 24H2

### Database and driver

TdEngine 3.3.3.2
taos-jdbcdriver 3.6.3

### Steps to reproduce

_No response_

### Additional context

_No response_

No source file, test, or entry point is identified. Start by reproducing the varchar display issue with DBeaver Community 25.1.2 on Windows 11 using TDengine 3.3.3.2 and taos-jdbcdriver 3.6.3, comparing the result with TDengine Explorer. Done means Chinese varchar values display as text rather than hexadecimal strings.
