How to enable Unicode?

Hello,

Thanks for this project, it's really useful. I'm using it for a little fortune demo over at

Do you know how to support Unicode characters in the terminal? Right now when the terminal shows Unicode characters, they are very garbled. One way to test is by typing this, which will get a Euro symbol if Unicode is being displayed properly: `echo -e '\xe2\x82\xac' `. When I enter that into the terminal on my Mac, I get a Euro symbol as expected. When I enter it into the terminal at , it comes out garbled.

I've tried building this myself with your Dockerfile and it comes out garbled in my build as well. I've tried to make a few changes too:

* Added the `locales` package via apt to your Dockerfile, and ran `sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen; locale-gen;`
* Added `BR2_TOOLCHAIN_BUILDROOT_LOCALE=y` and `BR2_ENABLE_LOCALE_WHITELIST="C en_US en_US.UTF-8"` to the buildroot config
* Created a custom busybox configuration with `make busybox-menuconfig` and setting `CONFIG_UNICODE_SUPPORT=y`, `CONFIG_FEATURE_CHECK_UNICODE_IN_ENV=y`, `CONFIG_UNICODE_COMBINING_WCHARS=y`, `CONFIG_UNICODE_WIDE_WCHARS=y`, `CONFIG_UNICODE_BIDI_SUPPORT=y`, `CONFIG_UNICODE_NEUTRAL_TABLE=y`, `CONFIG_UNICODE_PRESERVE_BROKEN=y`.

However, it still gives wrong output for Unicode symbols.

Do you know how to enable Unicode properly? Any help appreciated

For the record, here's what the incorrect output looks like in my image via the serial port (using xterm.js copied from v86). I get something similar over the video console, and on your demo at .
