Character Short Sale / Leerbuchstabenverkauf

It is a long tradition of historic and even contemporary information processing technologies to sometimes sell too short umlaut characters to their consumers. This form of short sale bets on the character to become invalid in the future.

In german we would call this a Leerverkauf -- empty sale.
Born as Martin Br?_samle, almost, I learnt to work around the issue.

Any questions?
