Convert UTF-8 accents to malformed ISO accents

Question

I'm in an UTF-8 project. I have data from an old ISO project where accents are bad encoded (é,è...), I don't want to convert the ISO data but I need to match some data between the 2 databases.

So I got to transform a "é" into a "é" (and so on..)

I tried to convert to ISO but I never succeeded to obtain the weird encodage.

Is there a way to convert these accents while staying in UTF-8 file encodage?

Answer 1

It really depends on which ISO encoding you were working with, but to (invalidly) "downgrade" from UTF-8 you could trying something like mb_convert_encoding('é', 'UTF-8', 'ISO-8859-1') , demo here
