Improve support for CJK characters

[ljvmiranda921]

Hi there,

Thanks for this tool. It has been really helpful!

I'm just having issues regarding Chinese/Japanese/Korean characters. Whenever they are encoded, they look garbled. I'm not sure if it's a UTF-8 parsing in the Rust or Python side.

Steps to reproduce

I've attached the sample input and output for this issue. Here's the minimum reproducible example

from qvd import qvd_reader
df = qvd_reader.read("sample_data.qvd")
df.to_csv("sample_data.csv")

Output
sample_data.csv

Hi thanks for raising the issue and providing a file to test. I've pushed a new version that should now support all UTF-8 strings.
