I just recently declined to buy (or pirate) an otherwise great game for this reason. I sent a polite email to the developers explaining this. It's really quite disappointing.
But it's not crucial. I'm perfectly happy with whatever text rendering my browser uses. I can read the results, and that is sufficient. Just let my browser render your text in accordance with my dictates, and don't try to interfere. You're less likely to break things that way.
Don't expect to stave off dehydration by drinking urine. Your body expels salts (and other substances) through urine. Thus you'll die from hypernatremia drinking urine or seawater, just as happens if you don't drink water at all.
Apparently blood and alcohol are also bad. They are processed as food, which requires large amounts of water from your body. Thus while they're both fluids, they result in a net loss of water.
Fish apparently have a column of fresh water near their spine. You can cut them open and drink from this. You can also suck fresh water from their eyes.
