Inserting text containing braces in pstricks

Question

I'ld love to create a Database-Symbol with pst-dbicons:

\rput(5.5,3.25){\database{3.5cm}{2cm}{Datenbank(en)}}

The problem is, that there are braces inside of the text. When I remove them, it works, but with the braces - no error - and no icon is drawn.

Any solutions?

Answer 1

\database needs an identifying name for the generated nodes. As default it uses the text of the third mandatory argument. But brackets do not work, because they will break the constructed name in PostScript: /N@Datenbank(en) is not a name token anymore. Therefore \database provides an optional argument at the end to specify an identification name:

\database{3.5cm}{2cm}{Datenbank(en)}[Datenbanken]

Note to implementors: This kind of problems are the reason for introducing \pdfescapename, \pdfescapestring and \pdfescapehex to pdfTeX that also works in DVI mode.

Package pdfescape also implements the escaping for e-TeX or vanilla TeX. The drawback is that \EdefEscapeName, \EdefEscapeString and friends are not expandable.

This allows an implementor to use arbitrary text for names or strings in PostScript or PDF that are written in a syntactically correct manner.
