This downloads, encodes, decodes, and verifies the icon:

include libcurl.e
CURLcode res = curl_easy_get_file(url,"",out) -- (no proxy)
if res!=CURLE_OK then
printf(1, "Error %d downloading file\n", res)
else
printf(1, "file %s saved\n", {out})
end if
string raw = get_text(out,GT_WHOLE_FILE+GT_BINARY),
b64 = encode_base64(raw),
chk = decode_base64(b64)
printf(1,"base 64: %s, same: %t\n",{shorten(b64,"chars"),chk==raw})</lang>
