What do you learn about the character of Odysseus through the poet's introduction in Book 1?

In Book I, we learn that Odysseus fought in the Trojan War, that he has been on the island of Ogygia for eight years, that Poseidon is planning to make his journey home extremely difficult because Odysseus blinded his son, and that his Odysseus' wife is surrounded by suitors who are ready to take his place.

I think that modern interpretations cannot come to an unambiguous opinion on this point.
The introduction actually reveals a lot about the character of Odysseus. It says that he was king of Ithaca and that he went to fight in the Trojan war, leaving behind his wife and infant son, Telemachus. Odysseus got lost on his way back, passing through Egypt and the land of the cyclopes (and other regions) before being able to get home (which took him several years to achieve).

Thanks for the indormation.
