Aah ok, we got us wrong here. It's the %something thing which isn't 
converted back into a Gambas UTF-8 string. It is not a problem about low 
or high byte first, that was a mistake I made when writing the mail.

When I read the POST string in, I get for example %C3%BC for "ü", so I 
have to convert these into UTF-8 characters for the string within Gambas 
to process them further.

My question should have been: Is there a ready-made function like conv() 
that is able to receive a 7-bit string in the form of %C3%BC and will 
convert it into a string with an ü?

And if conv() will do, which types of encoding will I have to use here?
