I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via
我想在Ctrl-Backspace中删除vim插入模式下的当前单词。从xterm内部我可以通过它来解决这个问题
:inoremap <C-H> <C-W>
but in gnome-terminal I cannot figure out a way to make it happen.
但在gnome-terminal中，我无法找到实现它的方法。
When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately,
当处于vim插入模式时，如果我键入control-v然后按退格键，我在xterm中得到^ H，而^？在gnome-terminal。不幸，
:inoremap <C-?> <C-W>
doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what.
在gnome-terminal中没有做到这一点; control-backspace无论如何都会删除单个字符。
Regarding ASCII codes:
关于ASCII码：
Gnome-terminal lets you change the backspace character under Edit -> Profile Preferences -> Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like
Gnome-terminal允许您更改编辑 - >配置文件首选项 - >兼容性下的退格字符。不幸的是，据我所知，没有选项可行：无论我通过设置应用于Backspace的任何字符，如果我尝试映射字符本身，就像
:inoremap <C-H> <C-W>
then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like
然后定期退格和控制退格都擦除整个单词;如果我尝试映射控制加上那个角色，比如
:inoremap <C-^H> <C-W>
then regular backspace and control-backspace just erase a single character.
然后定期退格和控制退格只删除一个字符。

gnome-terminal's libvte would need to be patched.
gnome-terminal的libvte需要修补。
libvte already has several options to map backspace, none of which distinguish Ctrl-backspace. It needs an option that does, maybe one that follows the behaviour of the linux console (^? for backspace, ^H for Ctrl-backspace). See this gnome bug.
libvte已经有几个映射退格的选项，没有一个选项可以区分Ctrl-backspace。它需要一个选项，可能是一个遵循linux控制台行为的选项（^？表示退格键，^ H表示Ctrl-backspace）。看到这个gnome bug。
2015 update: this was fixed in 23c7cd0f99d504cbab06d4c27254d4f3e2807ba8.
2015年更新：这是在23c7cd0f99d504cbab06d4c27254d4f3e2807ba8中修复的。
libvte 0.41.90, 0.40.3 and newer have the fix.
libvte 0.41.90,0.40.3和更新有修复。
