如何将X11 KeySym映射到Unicode字符? [英] How to map a X11 KeySym to a Unicode character?
问题描述
这是此文件的精确副本问题;但是，已接受的答案中链接的代码已有将近11年的历史了，代码中的此注释导致我提出了重复的问题:
This is an exact duplicate of this question; however the code linked in the accepted answer is nearly 11 years old, and this comment in the code leads to my duplicate question:
keysym-> UTF-8转换将有望由 通过XmbLookupString()的Xlib，理想情况下不必在X中完成 应用程序.但是我们还没有.
The keysym -> UTF-8 conversion will hopefully one day be provided by Xlib via XmbLookupString() and should ideally not have to be done in X applications. But we are not there yet.
我们到了吗?我知道XwcLookupString，但是类似...
Are we there yet? I'm aware of XwcLookupString, but something like...
wchar_t unicode = XKeySymToWideChar( keysym );
...将更加简单和逻辑，并且每次添加或更改KeySyms时都不需要更新.
... would be much simpler and logical, and not require updating whenever KeySyms are added or changed.
X11/Xlib中是否有一个简单的函数可以将KeySym映射到它的Unicode等效项?
Is there a simple function in X11/Xlib that will map a KeySym to its Unicode equivalent?
推荐答案
X11/Xlib中是否存在一个简单的函数，该函数会将KeySym映射到其 等价于Unicode?
Is there a simple function in X11/Xlib that will map a KeySym to its Unicode equivalent?
因为Unicode是Xlib发明的多年，所以没有人去过 回去添加这样的东西?大多数Xlib API是代码集 因为它是在每个语言环境都使用 不同的字符集(ISO 8859-*，Big5，JIS等)，因此 适用于当前语言环境的char缓冲区.有一些UTF-8 在以后的几年中添加特定的内容，但是大多数情况下，我们一直在尝试让 从那时起，Xlib放心，将新的API设计推向xcb 代替.
Because Unicode was invented years after Xlib and no one ever went back to add such a thing? Most of the Xlib API is codeset independent since it was written in the days when every locale used a different character set (ISO 8859-*, Big5, JIS, etc.), so you get a char buffer appropriate to the current locale. There were a few UTF-8 specific additions in later years, but mostly we've been trying to let Xlib rest in peace since then, pushing new API design towards xcb instead.
