I'm not challenging the claim that it contains a lot of texts; I'm challenging the claim that "everything has already been created and just needs to be found." That claim is explicitly false, regardless of the version of the Library of Babel you are using.
Edit: Reply to your reply:
One inherent limitation with the current code is that it has to assume some encoding. Currently, there is no encoding that contains all known glyphs (e.g the Prince symbol, uncommon kanji, etc) so there will be texts that can not currently be generated, regardless of how much you increase the character set.
Edit2: Even if one were to allow ASCII art to represent a character, you then have the problem of how to distinguish between ASCII art substitution and actual ASCII art. Consider "Densha Otoko," which basically consists of message board posts that often contain ASCII art.
