[Grml] sarge and kernel 2.6.18-grml: console and keyboard

console and keyboard:

man zsh*(something)

creates some unexpected special characters in the output instead of the foreseen text manipulations like e.g. underscore or ?? (bold works.) Keys Home (Pos1), End, Insert (Einfg) and Delete (Entf) dont work, but give a tilde on the console. Umlaute äöü ÄÖÜ dont work. Tried not very hard to find Lat15-Terminus16 in the repos-pool, did not succeed. where is it ? What is the fitting console font ? and where is it in repos? (booting with lang=de)

Thanks
