When new policies are chosen, for instance the use of endonyms
instead of exonyms in school atlases, this calls for measures
that help the users in dealing with endonyms from other languages.
These measures may consist of the application of the International
Phonetic Alphabet (see figure below), or for incorporation of
aids to pronunciation...

After World War II, in the German Democratic
Republic (DDR) hardly any exonyms were used for place names in
Eastern Europe, as this was considered to be proof of a revanchionist
attitude. After German reunification, this attitude changed and
German exonyms for placenames in Eastern Europe are again allowed.
Other changes in attitudes might bring with
them changes in spelling because of adaptation or rejection of
conversion systems between different writing systems that are
politically sensitive.
