(10401) order error with one language, other two works fine

[RodG]

Two things:
1. It would be much easier to rule out known PayPal bugs if you were using v1.3.9h instead of v1.3.9e. Is it possible for you to upgrade, and then test again?
2. If you can't upgrade, then please log a support ticket with PayPal at www.paypal.com/mts and submit this log file to them as part of the details, and ask them what specific part of the transaction is causing the 10401 in this case.

See Post#3
This has come a full circle. PayPal is a 'red herring'.

I thought you may be onto something with the prices though.

Summary: (See Post#13).
Problem only occurs with some *existing products* in the store.
There are 3 languages being used (English, German, Hungarian). The problem only occurs when using Hungarian language.
Problem is not in the language files.
I'm 99% convinced its a character encoding issue.
