glGetString和glGetShaderInfoLog等函数使用什么编码 [英] What encoding is used by functions such as glGetString and glGetShaderInfoLog

问题描述

OpenGL具有一些返回字符串的函数，例如glGetString和glGetShaderInfoLog.这些使用哪种形式的文本编码?

OpenGL has a few functions like glGetString and glGetShaderInfoLog that return strings. What form of text encoding is used for these?

我假设，假设它们以GLchar*的形式返回，则返回值中包含的是ASCII编码的文本，但这是否在任何地方指定了?

I assume, given that they're returned as a GLchar*, that it is ASCII encoded text contained in the return value but is this specified anywhere?

第二个相关的问题是，诸如glShaderSource和glBindAttribLocation之类的功能需要什么样的文本编码. GLSL程序是否必须用ASCII编码或可以是UTF-8?

As a second and related point, what text encoding is expected by functions such as glShaderSource and glBindAttribLocation. Do GLSL programs have to be encoded in ASCII or can it be UTF-8?

推荐答案

OpenGL 4.3兼容性配置文件规范，第22.2节，第627页:

OpenGL 4.3 Compatibility Profile Specification, section 22.2, page 627:

字符串查询返回指向UTF-8编码，以空值结尾的静态字符串的指针，这些字符串描述了当前GL上下文的属性.

String queries return pointers to UTF-8 encoded, null-terminated static strings describing properties of the current GL context.

据我所知，规范中并未提及glGetShaderInfoLog()的编码.

As far as I can see the spec doesn't mention the encoding of glGetShaderInfoLog().
