Hi! I suggest an update to libiconv 1.16, since the current Cygwin packages of libiconv 1.14 are old (updated 5 years ago).
Cygport files are forked to https://github.com/cygwin-lem/libiconv-cygport/tree/w_1.16 from http://cygwin.com/git/cygwin-packages/libiconv . New test package files are placed here: https://cygwin-lem.github.io/libiconv-cygport/index.html . Please, check them: x86/libiconv/libcharset1/libcharset1-1.16-1.hint x86/libiconv/libcharset1/libcharset1-1.16-1.tar.xz x86/libiconv/libiconv-1.16-1-src.hint x86/libiconv/libiconv-1.16-1-src.tar.xz x86/libiconv/libiconv-1.16-1.hint x86/libiconv/libiconv-1.16-1.tar.xz x86/libiconv/libiconv-debuginfo/libiconv-debuginfo-1.16-1.hint x86/libiconv/libiconv-debuginfo/libiconv-debuginfo-1.16-1.tar.xz x86/libiconv/libiconv-devel/libiconv-devel-1.16-1.hint x86/libiconv/libiconv-devel/libiconv-devel-1.16-1.tar.xz x86/libiconv/libiconv2/libiconv2-1.16-1.hint x86/libiconv/libiconv2/libiconv2-1.16-1.tar.xz x86_64/libiconv/libcharset1/libcharset1-1.16-1.hint x86_64/libiconv/libcharset1/libcharset1-1.16-1.tar.xz x86_64/libiconv/libiconv-1.16-1-src.hint x86_64/libiconv/libiconv-1.16-1-src.tar.xz x86_64/libiconv/libiconv-1.16-1.hint x86_64/libiconv/libiconv-1.16-1.tar.xz x86_64/libiconv/libiconv-debuginfo/libiconv-debuginfo-1.16-1.hint x86_64/libiconv/libiconv-debuginfo/libiconv-debuginfo-1.16-1.tar.xz x86_64/libiconv/libiconv-devel/libiconv-devel-1.16-1.hint x86_64/libiconv/libiconv-devel/libiconv-devel-1.16-1.tar.xz x86_64/libiconv/libiconv2/libiconv2-1.16-1.hint x86_64/libiconv/libiconv2/libiconv2-1.16-1.tar.xz -- Lem
