Replace Accented Characters - more comprehensive rule list already built?

Question

Hi,

I'm trying Kutools for Excel for the Replace Accented Characters function. I have a list of approximately 10k names that have to be converted from. I have found that the rule set included with Kutools is very limited. There are no capital letters defined, many characters missing, and no examples of certain letters that technically translate to two letters in English (e.g. þ converts to th in English). I realize with that example we're starting to cross the line from just accented characters to Latin characters.

But my question is, is there already a more comprehensive rule list out there I can import that would perhaps closely mimic the Normalize method of C#? It will take me days to manually add all these rules to the list in KuTools, and at that point I may as well just manually edit the names in the worksheet.

Thanks.
