New issue 398: Support logograms (like CJK characters) as account names.
https://bitbucket.org/blais/beancount/issues/398/support-logograms-like-cjk-characters-as

Alex Hou:

According to beancount language syntax, account names should follow this rule:

> Each component of the account names begin with a capital letter or a number and are followed letters, numbers or dash \(-\) characters. All other characters are disallowed.

But logograms \(Chinese characters, Japanese hiragana and katakana, Korean alphabet, etc.\) have no ‘capital letter’.

Please support these characters as account names.
