In case you want to include Sweden at one point as colonial power (seeing you're Swedish) here's the list of Swedish colonial possessions in their New Sweden colony 1638 - 1655. Had they not provoked the Dutch by taking the Fort Casimir (that they renamed Fort Trinity), the colony might have lasted few decades longer as Dutch New Netherland colony was taken over by English less than decade later.

I don't think removing storage limit of food and wood is such a good idea (it would look weird to have limitless store for some goods and limit to others and there needs to be limit for trade goods). I know it's bit harder to code but why not do as other colonization games (well sort of) and deduct goods needed divided by time needed to build per turn instead, this way say unit needing 250 wood and food taking 5 turns to build would use up 50 wood and food for 5 turns instead of 250 of both at once.
The main issue currently with unit upkeep is that the indian settlements are way too strongly defended. You need 12 units or more to take out a single one. If Indians had AI, Europeans would have to settle remote islands to survive as settlements on mainland would simply be wiped out as soon as they'd be established. Also there's the problem of indians having muskets from start as well. About 5-6 units (2 close combat, 2 musketeers and 1-2 canons) should be able to massacre almost any indian settlement exept maybe inca and aztec.
And to answer my own question about use of special characters : no, they are not supported.
Btw, there seem to be more maps in maps folder. Are they usable somehow?
