• Issue: Improve error message of UnicodeEncodeError in zoneinfo.load_tzdata #140145

As Serhiy has explained in the issue, this is wrong.

For example, on Unix you can see this with:

$ LC_ALL=C PYTHONUTF8=0 python3.14 - <<'EOF'
f = 'á.txt'
open(f, 'w')
EOF
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character '\xe1' in position 0: ordinal not in range(128)

So shell we still separate this or just leave this alone?

I saw your comment at the issue.

just leave this alone?

Closing as per issue.

Oh, wait, this was updated after my request. Reopening.

I'll skip news, while technically user-visible, it's a tiny change and unlikely many see this case in practice.

Merged, thanks.
