Fix PL/SQL Export Garbled Characters

Exporting table structure in PL/SQL may result in garbled characters due to incorrect encoding settings. The solution is as follows:

1. Make sure the character encoding setting for PL/SQL development tools is correct, typically UTF-8 encoding should be selected.
2. When exporting table structures, you can specify the character set by setting the NLS_LANG environment variable. For instance, you can set it to AL32UTF8 to ensure that the exported file is encoded in UTF-8.
3. When exporting table structures using tools like PL/SQL Developer, you can choose the correct character encoding format in the export options.
4. If the previous methods still cannot solve the problem, you can try using data export tools such as SQL Developer to export table structures. These tools typically automatically handle character encoding issues.

By following the above methods, you should be able to address the issue of garbled characters when exporting table structures in PL/SQL. If the problem persists, it is recommended to refer to relevant documentation or seek professional assistance.
