[EMAIL PROTECTED](XChar2b) == 2這個假設不成立。目前的狀況是：
1、glibc 2.1.3 locale/[EMAIL PROTECTED]
2、X locale除了和sizeof(XChar2b) == 2這個假設相關之外，其它正常。
3、XDrawString16基本正常，可以畫漢字(問題在後面)。
所以如果是:
char *ch_str = "zh1 zh2 zh3 zh4";
...
XDrawString16 (display, window, gc, x, y, (_Xconst XChar2b *)ch_str, length +
1);
看到的是
zh1 zh2 zh3 zh4 00
如果是:
XChar2b *ch_str = struct copy "zh1 zh2 zh3 zh4";
...
XDrawString16 (display, window, gc, x, y, (_Xconst XChar2b *)ch_str, length +
1);
看到的是
zh1 00 zh2 00
XmbDrawString/XwcDrawString在漢字部分就是這樣顯示。如果想保持代碼的效率，只有在
gcc for [EMAIL PROTECTED] CPU要求尋址按字(word)對齊，所以只要把gcc for ARM
的缺省編碼按字對齊而不是按雙字(dword)就行了。
XDrawString16的問題：
[EMAIL PROTECTED]|[EMAIL PROTECTED]@個漢字(規律還沒有找到)。程序自己刷新窗口
就正常了。
[EMAIL PROTECTED] = length + 1。刷新窗口也沒有用。
問題的原因還在查找，我猜想可能和sizeof(XChar2b) == 4相關。
