They say the limit isn’t enforced on the protocol level (but as far as I can tell, that’s also not true - fixed bugs in parsing of long descriptions and texts · CounterpartyXCP/counterparty-lib@3127aa8 · GitHub).
I do know that it is enforced in the CLI because I tested this few weeks back.
Here it says from August 2014 and on Testnet, there’s no 41 char limit.
Well, I just changed description on mainnet, for a “paid” (letters-only) asset, to 52 characters.
It worked fine so as far as I am concerned there’s no issue - Counterwallet allows 52 characters for both mainnet and testnet (and maybe more is possible).
If anyone has a problem they should try a different client (Indiesquare Wallet?) or another browser or the CLI.
It also cost me 0.00032076BTC which is more than I was expecting as I read the docco and I thought it said “fee 5430 satoshis (0.05USD) and 0.0001 BTC tx fee (0.1USD)” ?
The minimum transaction fee, yes. But it can be, and usually is, higher. And if you operate from a multisig address, you can pay triple as much.
