Upgrade 1.3.4 --> 1.4.2 : Problem with charset?

[whmeeske]

First I used CPG 1.3.4 without any problems.
Today I upgraded to CPG 1.4.2.

Now I discovered a problem with presentation of some characters. My language is set to Dutch with charset default
For example, the character 'ë' is not presented correctly. The word 'categorieën' is shown as 'categorieën'.

Is there a way to solve this problem?
If not, then I'm forced to go back to version 1.3.4.

I've the same problem with Italian language, "à" "è" "ì" "ù"  "ò"  "é" are displayed as "Ã" and one more symbol after.
