Tried this in HL and CS and does not show the console when pressing ö. Only § works (default) shows it. This on a Swedish keyboard layout set.
same problem here, reported it here as well:

dupe of ValveSoftware/halflife#19, and we are moving to the halflife/ tracker so closing this out
Nothing extracted yet.
The character ö incorrectly toggles the console on finnish and swedish keyboard layouts.
