Not entirely true. From the link I provided earlier:
<q>
Nonquoted identifiers can contain only alphanumeric characters from your
database character set and the underscore (_), dollar sign ($), and pound
sign (#). Database links can also contain periods (.) and "at" signs (_at_).
Oracle strongly discourages you from using $ and # in nonquoted identifiers.
Quoted identifiers can contain any characters and punctuations marks as well as spaces. However, neither quoted nor nonquoted identifiers can contain double quotation marks or the null character (\0).
</q>
