I want to use newlib's libiconv for converting utf8 to iso-8859-11.
Is there any example to using iconv on Arduino-ESP32 or ESP-IDF?

Thank you.

Still no official iconv support in both the toolchain and IDF.

You can try build your code which uses iconv.h with https://dl.espressif.com/dl/toolchains/preview/xtensa-esp32-elf-gcc8_2_0-esp-2019r2-41-g8ac0429-linux-amd64.tar.xz (iconv support enabled ) and give any feedback here.

Probably the support for iconv.h will be added to next release of the toolchain (2020r1)
