This patch fixes broken layout of some commands when there is Unicode text in the ledger file. I substituted System.IO functions with System.IO.UTF8. Now all strings are Unicode internally, and take's and length's work correctly. In particular, add, balance, hist, print and register commands seem to work correctly; ui is still broken for me, I didn't try web. I decode command line arguments from UTF8 forcefully, to permit searches for accounts and descriptions with Unicode (otherwise, it does not work). The patch adds an additional dependency: utf8-string. This patch does not include new test cases.
