设置中文字体出现如下错误：
there is either a configuration problem with TrueType or a problem reading font file ("/web/docs/fonts/simhei.ttf).
Make sure file exists and is in a readable place for the HTTP process. (If 'basedir' restriction is enabled in PHP then the font file must be located in the document root.) It might also be a wrongly installed FreeType library. Try upgrading to at least FreeType 2.1.13 and recomple Go with the correct setup so it can find the new FT library.
