commit https://github.com/vim/vim/commit/7ce686c990ea8c490d16be7f1c6bd95eb48816f9 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Feb 27 16:33:22 2016 +0100 patch 7.4.1430 Problem: When encoding JSON, turning NaN and Infinity into null without giving an error is not useful. Solution: Pass NaN and Infinity on. If the receiver can't handle them it will generate the error.

let s:encoding = &enc
if s:encoding == 'latin1'
    if has("unix")
	let s:encoding = 'iso-8859-2'
    else
	let s:encoding = 'cp1250'
    endif
endif

if s:encoding == 'utf-8'
	source <sfile>:p:h/croatian_utf-8.vim
elseif s:encoding == 'cp1250'
	source <sfile>:p:h/croatian_cp1250.vim
else
	source <sfile>:p:h/croatian_iso-8859-2.vim
endif
