I decided to build iconv myself to resolve this issue. I've made it available in a usable form, so if you're still in trouble, try it out. https://github.com/sidepelican/xciconv

@bmanahilov All my build steps are written in https://github.com/sidepelican/xciconv/blob/main/build.sh. Check it out. It is built in library mode, so almost all of the symbols are prefixed with lib. (e.g., iconv_open -> libiconv_open)
