How Can I Ensure Correct Display of Unicode Characters When Writing to a Text File in Python?

Handling Unicode Characters in Text File Writing

Writing non-ASCII characters to text files requires careful consideration of character encoding. The question explores the use of Unicode in data processing and encounters an encoding error while writing to a file.

The partial solution replaces the problematic codec with Python's open function, which opens a file in binary mode by default. While this solves the decoding error, it introduces another issue: the characters are not correctly displayed in the text file.

To resolve this, it's crucial to handle Unicode exclusively throughout the process. Converting data to Unicode objects upon retrieval and encoding them only when necessary ensures proper character representation.

The following modified Python code exemplifies this approach:

<code class="python">import unicodedata

row = [unicodedata.normalize('NFC', x.strip()) if x is not None else u'' for x in row]
all_html = row[0] + "<br/>" + row[1]
with open('out.txt', 'wb') as f:
    f.write(all_html.encode("utf-8"))</code>

By normalizing Unicode to the NFD form, the text can be consistently represented as NFC across platforms, ensuring correct display in the text editor.
