Define macros in examples/unicode.h to use Unicode argv on Windows. Keep char everywhere on Unix since it handles UTF-8 without any change. Impact: - All fopen () and SHCreateStreamOnFile(), - All fprintf() printing file paths, - All strcmp() used with "-", - File path parsing, - Gif reading. Concerned executables from examples/ and extras/: anim_diff, anim_dump, vwebp, vwebp_sdl, cwebp, dwebp, gif2webp, img2webp, webpmux, webpinfo, webp_quality, get_disto When compiled on Windows with Unicode enabled, webpmux and img2webp will not work when used with an argument file and will print "Reading arguments from a file is a feature unavailable with Unicode binaries."
