And don't forget another german letter: ß = ss.
But use those only for german words or names. Not for any nordic languages like finnish (or swedish?). Never insult us finns by using german replacements for letters ä and ö in finnish names or words. Finnish word "hä" and "hae" sound different and have totally different meaning. Hä = what? (an unofficial but common dialect form) Hae = fetch!
If You can not use proper letters to print for example Mika Häkkinen's last name (The F1 Champion 1998 and 1999) then write like he wants it to be written internationally: Hakkinen.
NEVER!!! Haekkinen. That would be wrong. Totally wrong.
