Unicode do not exist in languages written in the Latin script. At translatewiki.net we got the request to replace characters with the correct characters for the Hungarian language.
Before Unicode, the characters available were defined in the ISO basic Latin alphabet. In Hungarian, like in other languages, they made do with what was available.
As Unicode has found its way on the Hungarian keyboards, such throwbacks are no longer necessary. It is wonderful that these replacements will be made wherever necessary in an automated way.
