[TxMt]sorting by custom sort order

Hi everyone,

I am looking for a way to sort lines in a simple txt file for a wordlist/dictionary project. I know that in Textmate there is the

Bundles>Text>Sorting where I can sort the line alphabetically

according to latin based graphemes. My problem is that I am using IPA symbols a lot in the wordlist, e.g. ɸ, ⁿt, ð. The sort order in the Text bundle treats IPA characters as special symbols and puts them at the end, which is not what I want. So I was wondering if there is way of creating a custom sort order and apply it. For example: "a,æ,b,ᵐb,d,ⁿd,e,ɸ ..." instead of "a,b,c,d,e,f ..."

Best
