SQL with umlauts get bricked

[flashspys]

So I've a postgrse schema named "Köln".
By pressing CTRL+I the SQL

SELECT
  *
FROM
  köln.tier
```sql
will be formatted to:
```sql
SELECT
  *
FROM
  k ö ln.tier

effectively bricking this sql code.

It looks like this is a common problem with sql-formatter, and sql-formatter-plus has this bug already fixed
