Ok, It was a mistake to think that I, a teacher who likes programming during his sparetime, could keep up with the pace of Moodle development. I upgraded most of these blocks for 1.5, but I fear the utf conversion for Moodle 1.6 is one step too much. 
I've already dropped the random picture block and the time block, but I really need the configurable search block. Teachers have already added different search engines to that block and I would really like to keep it.
Since the quite silly implemented random quote block I've learned most of the stuff by looking at other people's code. I tried looking at the source code for the conversion scripts, but I can't really grasp what's the point. I can't really find good documentation on writing the conversion scripts either.
Is there someone willing to take a look at the code of the multiple search block and help me understand which fields exactly need which utf8 conversion?
The multiple search block is a block I wrote to replace the different wikipedia / webster / moodledocs / dictionary / google / blocks used on our school site. Code and some explanation with a screenshot can be found in this discussion
and here
TIA
