UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 970: character maps to <undefined>

After installing the library with pip and trying to initialize it, I'm getting the following error:

Traceback (most recent call last):

epi = epitran.Epitran("eng-Latn")
It does not matter what language.

Python 3.12.5
epitran 1.25.1

Just to confirm that I have exactly the same issue with "deu-Latn"

Has this problem solved?

My error is: UnicodeDecodeError: 'gbk' codec can't decode byte 0xa3 in position 7832: illegal multibyte sequence.
So I modified panphon's code to force the file to be read using utf-8 encoding:

1. Open the panphon/featuretable.py file.
2. Find the _read_bases function, it should be in line 76.
3. Modify the Open () function and specify the encoding to be utf-8, like

with open(fn, encoding='utf-8') as f:
    reader = csv.reader(f)
    header = next(reader)
    ...

This solution is effective for me, but I think it is temporary.

I'm having the same issue on Windows 11 with the most recent Python and Epitran versions.

I had the same problem, it's expecting an utf8, but it gets different format, just paste this in your terminal and run it again:
$env:PYTHONUTF8=1
