Using other than the default font would disorder the text spacing in Terminal

[kutspam@…]

For revision of may 9th I changed fonts in the terminal (for checking if special Czech characters / glyphs which were missing in the other fonts as well) and by this the space between characters was wider and some additional tabs were rendered. Bluntly said; a mess were I couldn't tell were the end of the line was because when I would backspace it would delete more than I wanted to. Sort-of don't know where the cursor is.
