What steps will reproduce the problem?
1. Update database with an entry that has certain unicode characters

For instance, in a file with "René van den Enden" as the developer of a game, 
RCB crashed with the following error:

Error:

er V0.5

In addition to "é", I have encountered this error with "²" (superscript). 

It appears that the crash is only related to error logging?

What version of the product are you using? On what operating system?
RCB 0.5, 64 bit linux

It's a wonder that Magnavox never released pong for the Odyssey 2 back in the 
day. Rene van den Enden has done an excellent job with this game of speed and 
skill. Play solo or against an opponent in this blast from the past! There are 
11 variations of Pong, from Squash to Tennis, to the original classic and more. 
Keep the ball in play as long as possible for the winning high-score or best 
time! Significant to this release is that this cartridge version is 
significantly better than previous releases. The game is now 4K and offers many 
more Pong games and variations.

I think that I have fixed this one, too. But I will test this with the current 
version again.
