Stellar UTF-8 Support We are developing the open government auctions system on “Stellar” platform.  We forked Stellar and run our own network. We’ve added Lot creation transactions, auction participation, bids etc. There is encoding problem. We tried this solution:  https://github.com/stellar/js-stellar-base/issues/60 But during the debug process we’ve find out that Stellar-core can’t process the data sent by js-xdr library in base64 (UTF-8) format. We’ve looked at the C++ source code but haven’t found the way to fix that.

Error example: 
{\"exception\"=>\"Non-zero padding bytes encountered\"}"

Some help and/or advice on this issue will be much appreciated.

The problem was in count of characters encoded in tx. C++ code allocate memory depending of count variable in tx. 
This commit solve the problem: https://github.com/stellar/js-xdr/pull/4/commits/119a8c26f71de8568d88cee1a94cb33074797859
