What is PostgreSQL EUC_TW_TO_BIG5()?

PostgreSQL EUC_TW_TO_BIG5() is a function that is used in the PostgreSQL database management system. It is specifically designed to convert text encoded in the EUC-TW character set to the BIG5 character set. EUC-TW is a character encoding used for traditional Chinese text in Taiwan, while BIG5 is another character encoding widely used for traditional Chinese text. This function allows users to seamlessly convert text between these two character sets, ensuring compatibility and proper display of traditional Chinese characters in their database applications. By utilizing PostgreSQL EUC_TW_TO_BIG5(), users can efficiently handle and manipulate traditional Chinese text data within their PostgreSQL databases.

Why use PostgreSQL EUC_TW_TO_BIG5()?

PostgreSQL EUC_TW_TO_BIG5() is a useful function for those who work with traditional Chinese characters in their database. This function is specifically designed to convert text encoded in the EUC-TW (Extended Unix Code for Traditional Chinese) encoding to the BIG5 (Chinese character encoding standard) encoding. By using this function, users can ensure that their data is accurately represented and can be easily processed and displayed in applications that require the BIG5 encoding. This function is particularly beneficial for developers and businesses operating in regions where traditional Chinese characters are commonly used, as it simplifies the handling and manipulation of text data in their PostgreSQL databases.


The correct syntax of the PostgreSQL EUC_TW_TO_BIG5() function is as follows: EUC_TW_TO_BIG5(input_string). This function is used to convert a string from the EUC-TW encoding to the BIG5 encoding in PostgreSQL. The input_string parameter represents the string that needs to be converted. It is important to note that both the EUC-TW and BIG5 encodings are specific to the Chinese language. The EUC_TW_TO_BIG5() function can be useful when working with Chinese text data in a PostgreSQL database, allowing for seamless conversion between different character encodings.


In this blog post, we will explore the usage of PostgreSQL's EUC_TW_TO_BIG5() function and provide code examples to demonstrate its implementation. The EUC_TW_TO_BIG5() function is a character conversion function in PostgreSQL that converts text from the EUC-TW encoding to the BIG5 encoding, which are commonly used in traditional Chinese text processing. To use this function, you need to have PostgreSQL installed and a database set up. Once you have the prerequisites in place, you can execute the EUC_TW_TO_BIG5() function by passing the text you want to convert as an argument. Let's dive into some code examples to illustrate its usage:

Example 1:
— Output: 妳好世界

Example 2:
— Output: 臺灣

These examples demonstrate how the EUC_TW_TO_BIG5() function converts text from the EUC-TW encoding to the BIG5 encoding. By utilizing this function, you can ensure accurate and consistent character conversion in your PostgreSQL database.


In conclusion, the PostgreSQL EUC_TW_TO_BIG5() function is a powerful tool for converting text data between the EUC-TW and BIG5 character encodings. By utilizing this function, users can seamlessly handle and manipulate data in different encodings, ensuring compatibility and accuracy in their PostgreSQL databases.

This blog post has explored the functionality and usage of the PostgreSQL EUC_TW_TO_BIG5() function, highlighting its importance in multilingual environments, particularly in Taiwan where the EUC-TW and BIG5 encodings are commonly used.

We have discussed the syntax and parameters of the function, providing examples to demonstrate its practical application. Additionally, we have emphasized the significance of proper encoding conversion in maintaining data integrity and enabling efficient data processing.

By incorporating the PostgreSQL EUC_TW_TO_BIG5() function into your database operations, you can effectively handle text data in different encodings, enabling seamless communication and data exchange across various systems and platforms.

In conclusion, the PostgreSQL EUC_TW_TO_BIG5() function is a valuable asset for developers and database administrators working with multilingual data in Taiwan.
