Hello Mathias,
1. You have to use unicode (either directly or in UTF8 encoding) for
the special characters:
std::vector<std::wstring> lines;
lines.push_back(L"Taste dr\u00fccken");
(direct unicode) - mind the L before the string constant, this is
*not* a typo! Or:
std::vector<std::string> lines;
lines.push_back("Taste dr\xc3\xbc""cken");
(UTF8 encoding) - the two quotes prevent the compiler from treating
the following 'c' as part of the hex escape sequence.
2. The texture that contains the characters by default just contains
the printable ASCII characters between 0 and 127. You have to tell
OpenSG which characters you actually need when you create the face.
For example, the following code adds the german upper- and lowercase
umlauts and the sz ligature:
OSG::TextTXFParam txfParam;
std::wstring characters = txfParam.getCharacters();
characters += L"\u00c4\u00d6\u00dc\u00e4\u00f6\u00fc\u00df";
txfParam.setCharacters(characters);
OSG::TextTXFFace *face = OSG::TextTXFFace::create("SANS",
OSG::TextFace::STYLE_PLAIN, txfParam);
Again, mind the L before the string constant.
Bye,
Patrick
