我的版本：

解決漢字亂碼的問題，一句話說就是調整字體為宋體

之 后會打開對話框：
之 后注釋中就可以正常輸入中文了，字距正常。< br>
下面是一個宏定義文件，綁定了Backspace，讓它能正確刪除一個漢字。
需要先關閉當前項目，打開Base項目，這個Base項目是Source Insight為你自帶的，代表項目的項目設置，你的其它自建項目應該是以它為基礎。

會 打開下面的對話框，在其中選擇Base項目打開。

在Base Project中，新建一個SuperBackSpace.em文件，把下面所給出的代碼寫到文件中保存到 Base 項目中：
在項目文件列表中用右鍵單擊:
然 后，打開鍵綁定對話框：
會 打開下面的對話框：剛才添加進來的宏定義文件中新定義的宏 SuperBackspace就列在下面 Command 一欄。

在 Command:下面的字體框中輸入Mac, 下面的列表會只顯示以Mac開頭的項。這樣很容易就選擇到了這個宏，然后點擊"Assign New Key..."按鈕， 彈出下面的對話框，
此時按下退格鍵（Backspace），"確定" 退出即可。設置成功后該對話框顯示為：

此 時再試一下退格鍵，可以成功刪除一整個漢字了。但是：
用鼠標選擇注釋中的漢字部分，仍然可以選中“半個“漢字，此時顯示為亂碼。
而 用左右箭頭鍵移動光標時，仍然可以移動到一個漢字的半中間，就是說移動光標仍然是半個漢字為單位。

上面 一行是鼠標選中半個漢字的情況，下面的那行是光標移到漢字“中”的半中間時，光標閃爍至剛好顯示那個小棍棍時的截截。
另外。在base 項目中選中 SuperBackspace.em 本身，在下面的Context窗口中可以看到該文件的內容，這個文件開頭的部分是中文注釋，顯示為亂碼，在Context中右鍵單擊，改變字體為宋體，仍 然會顯示亂碼，漢字有的能正常顯示，有的則不能。

Source Insight對漢字的支持，說一句糟糕真不過分。

使用下面的一個宏，即 Project→Open Project，

打開Base項目；

新建一個SuperBackSpace.em文件，將下面的代碼加入進去并保存，

把SuperBackSpace.em文件復制到Base工程的工程目錄下。選擇【Project】→【Add and Remove Project Files...】打開對話框，加入SuperBackSpace.em文件 ；重啟 SourceInsight；

打開Options→Key Assignments（對話框）

將Marco: SuperBackspace綁定到BackSpace鍵（在Key Assignments 對話框中先選中Commant 一欄的Marco:SuperBackspace,然后點擊按鈕“Assign New Key” 會彈出一個提示框，接著用手指按下鍵盤上的“Backspace”鍵，然后再點擊“是/YES”，最后在點擊“OK/確認”這樣 就可以了，下面類似）

Marco: SuperCursorLeft綁定到 <-鍵 ，

Marco: SuperCursorRight綁定到 ->鍵 ，

Marco: SuperShiftCursorLeft綁定到 Shift +<- ，

macro，SuperShiftCursorRight綁定到 shift +-> ，

Macro：SuperDelete綁定到del。

代碼：

注：如果加入SuperBackSpace.em 后出現非法關閉sourceinsight 則需要把原先自帶的utils.em從base項目中去掉才行，去掉不影響使用，我的就是出現了這個問題，結果異常關閉之后，每次再打開都是自動異常關閉，最后不得已刪除我的文檔中的sourceinsight目錄，然后重裝才搞定，所以最好在Add and Remove Project Files...】SuperBackSpace.em 時，把utils.em給去除掉。

改進Source Insight對漢字的支持
