Problem: By default, aq.fromCSV(csv, { header: false }).orderby('col1').toCSV()Correct order would be: One can achieve that by using (lhs, rhs) => lhs.localeCompare(rhs, 'tr-TR');Is there a way to feed this comparator to the Arquero somehow? |

There is not a mechanism for this at present. Currently Arquero relies on standard JS comparison operators. I'll open a feature request issue for this. |

Arquero version 7.1.0 now includes a aq.fromCSV(csv, { header: false }).orderby(aq.collate('col1', 'tr-TR')).toCSV()The collate method accepts either arguments compatible with the Intl.Collator constructor (such as a locale string) or a two-argument custom comparator function. |

Arquero version 7.1.0 now includes a
collatehelper function to support custom string orders. You can use it in your example above like so:The collate method accepts either arguments compatible with the Intl.Collator constructor (such as a locale string) or a two-argument custom comparator function.
