Thank you very much, tshering, for this patch. I only increased the font size in the dictionaries, but that makes an awful difference for me. Actually, I didn't use your patch, but modified libnickel.so.1.0.0 directly (first I DID change the length of the respective section in libnickel.so.1.0.0, so I had to make a factory reset

). Now all is fine. I have a Kobo Mini, used font-size:26px;line-height:30px and did not change font-family. By the way, if someone uses only dictionaries he produced with penelope.py, penelope.py can be modified to define the font-size one likes without modifying libnickel.
