Need program to convert UTF-8 -> Hex sequences

[David Oftedal]

Hello!

Sorry to make this a mass spam, but I need a program to convert UTF-8 to 
hex sequences. This is useful for embedding text in non-UTF web pages, 
but also for creating a Yudit keymap file, which I'm doing at the moment.

For example, a file with the content æøå would yield the output "0x00E6 
0X00F8 0X00E5", and the Japanese expression あの人 would yield "0x3042 
0x306E 0x4EBA".

Can anyone tell me how to do it without making a program for it myself? 
It would be VERY helpful, and I've already made 2 programs for 
assembling this file and I'm not starting on another just yet.

Best regards

David J. Oftedal
