Should I be typing in Japanese? Hey I could be wrong. The error message that comes up is that 2 characters will congest the network, as it will seek out/search thru more items than it could possibly need & without necessarily finding all possible desired sources before the search is exhausted. In other words, a lot of search energy would simply be wasted searching thru unnecessary & unwanted files. One thing the p2p & particularly LW designers try to do is limit unnecessary traffic along the Gnutella network so it doesn't work at snail's pace. Which would you prefer, LW to work as the tortoise or the hare? lol
If you're refering to Asian characters such as used in Chinese or Japanese then perhaps you should put a request in for a new feature in LW. Post here:
