Unicode decode issue #506

Open CXPhoenix opened 3 years ago

Eel version: 0.14.0 OS: Win10 Enterprise 20H2

Hi, It's honor to use this wonderful library. But when I create the first simple application, there's some issue about unicode decode problem.

Here's the error in runtime:

'***' is my user name

Hello, This issue is quite old, but for anyone having the same issue, I spent some time digging around and adding breakpoints, the issue on my side was due to my machine's name which had an unsupported utf-8 character (in my case, "ë"). To solve the issue, go to Parameters > System > About > Rename this PC, and rename the PC with a simple name (without special characters). This solved the issue on my side !
