If I recode base64 encoded data with my modded base64 encoder (you will have to include small 288 byte decode function with data to unpack) that uses spaces as one of the characters, I can now achieve decent compression with server side gzip of average 2% (few times over 10%) compared to 1% gained (usually gets bigger) before with embedded bzip …

modded-base64.js

function fake_btoa(a) {
  var c, d, e, f, g, h, i, j, o, b = "WHAK.com/PaCker BDEFGIJLMNOQR\
  STUVXYZbdfghijlnpqstuvwxyz+01234567=", k = 0, l = 0, m = "", n = [];
  if (!a) return a;
  do c = a.charCodeAt(k++), d = a.charCodeAt(k++), e = a.charCodeAt(k++), j = c << 16 | d << 8 | e, 
  f = 63 & j >> 18, g = 63 & j >> 12, h = 63 & j >> 6, i = 63 & j, n[l++] = b.charAt(f) + b.charAt(g) + b.charAt(h) + b.charAt(i); while (k < a.length);
  return m = n.join(""), o = a.length % 3, (o ? m.slice(0, o - 3) :m) + "===".slice(o || 3);
}

function fake_atob(a) {
  var b, c, d, e = {}, f = 0, g = 0, h = "", i = String.fromCharCode, j = a.length;
  for (b = 0; 64 > b; b++) e["WHAK.com/PaCker BDEFGIJLMNOQR\
  STUVXYZbdfghijlnpqstuvwxyz+01234567".charAt(b)] = b;
  for (c = 0; j > c; c++) for (b = e[a.charAt(c)], f = (f << 6) + b, g += 6; g >= 8; ) ((d = 255 & f >>> (g -= 8)) || j - 2 > c) && (h += i(d));
  return h;
}

Need to experiment more, find where the space makes most impact, maybe add in tabs too, have too see...

Wonder how many times now I can recompress things before they start getting bigger. My 1.44MB Holy Bible app was originally 6MB, minified JavaScript/Jquery (down to 5.3 MB), WHAK packed HTML (brought to about 4MB), compressed to bzip, then gzipped. Gzip alone only achieved 2.3MB and bzip alone only got 1,8MB. Here is my 1.44 (fits on floppy) portable Bible app: http://holybibleverse.master.com/texis/master/search/ and now I might be able to recode it with my little hack and get it down another 10% or more!

Maybe randomizing the character map will help me find a "sweet spot"...

Let web user use his/her own custom string for character map using only available characers so they may make vanity like mine

Function to pack pure JavaScript code in WHAK64 encoding:
