CJK characters should be count as 2-char width

[Jack-Works]

The formatter currently counts CJK chars as 1 char width which creates a bad format result:

Current format result:

2024-01-01 *
  Assets:Test:一二三銀行-A                                       10 JPY
  Assets:Test:一二银行-B                                        20 CNY
  Assets:Test:은행                                            30 WON

Expected result:

2024-01-01 *
  Assets:Test:一二三銀行-A                                       10 JPY
  Assets:Test:一二银行-B                                         20 CNY
  Assets:Test:은행                                               30 WON
