osgText如何显示中文

wontor

以前用setText(L"你好"）是可以的，但是现在在mingw下，osg2.3.7下编译的时候，说不合法的字符串
高手给点建议。谢谢。

FlySky

设置一下使用中文字体text->setFont( "fonts/simhei.ttf" );～～～～～～～～～～～～

FlySky

不过，没有设置字体应该不会出现非法字符串的～～～～有可能是你的编译配置问题～～～～～～
最好贴出一段代码或者把工程上传过来看看～～～～～～～～～～

mingw下面前面不加L吧应该

wontor

如果
        osg::ref_ptr<osgText::Text> text = new osgText::Text;
        text->setText(L"HELLO WORLD");
正常能过，并能够正确显示

如果
        osg::ref_ptr<osgText::Text> text = new osgText::Text;
        text->setText(L"HELLO WORLD 你好");
则编译的时候会有如下错误：
main.cpp:13:16: converting to execution character set: Illegal byte sequence

如果为：
        osg::ref_ptr<osgText::Text> text = new osgText::Text;
        text->setText("HELLO WORLD 你好");
那么编译通过，但只会显示HELLO WORLD ，但不会显示“你好”

大概这是g++的问题
试一试加上编译器参数-finput-charset=GB2312

osg::ref_ptr<osgText::Text> text = new osgText::Text;
        text->setText("HELLO WORLD 你好");
这种情况下你再设置一下使用中文字体simhei.ttf字体，否则中文无法正常显示：text->setFont( "fonts/simhei.ttf" );
这样应该就可以了吧～～～～～～～～～～～～～···

首先表示感谢。
mingw上g++编译器的确有这个问题，我用一个最简单的语句测试了一下，用这个选项可以顺利编译，如用不用就会不通过。

但是对于OSG代码，我加上-finput-charset=GB2312选项后，会有一大堆的错误，都是关于OSG的。

晕了。

我在代码中已经有text->setFont("fonts/simkai.ttf");
换成text->setFont( "fonts/simhei.ttf" );以后效果一样，HELLOWORLD正常显示，像“你好”不显示。

呵呵，什么错误？能提供一点错误文字信息吗
