New issue 161: Unicode support

rutsky:

I believe this issue arised [several](https://groups.google.com/d/msg/ledger-cli/C6GOOj8kGtQ/6pGThn3DRTIJ) [times](https://groups.google.com/d/msg/beancount/vVzzfE3m_ow/usM6Ft6-zi0J), but haven't found ticket for it with information about current status and plans.

For example, I want to have account name with Unicode characters in it. As I see beancount currently doesn't support that:

```
$ cat test2.beancount
option "operating_currency" "RUB"

2014-01-31 open Assets:Imbalance-RUB RUB
2014-01-31 open Assets:Orphan-RUB RUB
2014-01-31 open Assets:Активы RUB
$ bean-check test2.beancount
/home/bob/stuff/money/test2.beancount:5: Invalid token: 'Assets:Активы'
$ pip list | grep beancount
beancount (2.0b15)
```

I'm trying to switch from Gnucash to Beancount (with [gnucash-to-beancount](https://github.com/henriquebastos/gnucash-to-beancount) converter tool), and limiting account names to ASCII is a showstopper for me.

What is the current status of Unicode support (in account names and other entities)?

What are the plans to support Unicode everywhere?

Maybe there are known workarounds?
