I am working in a project which will make use of IPA symbols in some tables and Oracle 11g, and I want to know if these symbols are supported and if I should take some precautions when creating the database, schema and tables.
By the way I am new to Oracle 11g but it is compulsory for to work with it.
Assuming that "IPA symbols" refers to the International Phonetic Alphabet, those characters should all be available in the Unicode character set. When you create your database, you'll need to ensure that you are using a Unicode character set (AL32UTF8). And you'll need to ensure that your application supports Unicode.
