Hello,

I've tried many different ways when compiling the Erlang package to enable UTF8 support but each time it ends up using the latin char-set.

Things I've tried:
- export `LC_CTYPE and LC_ALL` with a value of `en_US.UTF-8` during compile time
- export the same vars above when running the interactive prompt

Erlang code used to test if UTF8 is enabled:

1> lists:keyfind(encoding, 1, io:getopts()).
2> io:format("~ts~n",["Paměť"]).

Returned values:

1> {encoding,latin1}
2> Pam\304\233\305\245
   ok

What else can I do to try and enable UTF8 support in Erlang?

I am not sure if I can be of any help. However, according to this Using Unicode in Erlang, it says the encoding default for Erlang source files was switched to UTF-8 in Erlang/OTP 17.0. The current OpenWRT erlang package is version R17.5 and should have UTF-8, AFAICT.

@mazilo thanks for the answer but that only applies to the files and not the VM that Erlang code compiles down to and runs in.

Sorry, I can't be of any help on this.

After much digging around the Erlang docs I found out that I need set the env var of ERL_FLAGS to '+fnu' in the shell to enable UTF8 support in the Beam VM.
