首先確保
data.txt的換行字元（Newline Character）是CR+TF(Windows)
Encoding是UTF-8 without Signature
如果不按這個標準來，很容易出現詞條數目對不上。
下面正式進行troubleshooting:
1.Invalid keyword at position
這是最常見的問題之一，可以使用谷歌搜尋：
site:pdawiki.com Invalid keyword at position:
Begining loading source file...
Content is longer then 8388608 at position: 0 of the source file
Failed to load source file, process cancelled
Begining loading source file...
Invalid keyword at position: 155387606 of the source file
Failed to load source file, process cancelled
Begining loading source file...
Invalid keyword at position: 155387606 of the source file
Failed to load source file, process cancelled
可能是某個詞頭缺失，導致</>的上一行，是空行。
可以在sublime text中開啟檔案，使用正則搜尋搜尋：
^\s\n
把詞頭新增上去即可。
如果想要精確定位到position: 155387606
可以在notepad++中開啟檔案，然後在Search > Go To（或者直接快捷方式：Ctrl + G），在彈出的皮膚中，選擇Offset，把155387606輸入，按OK，即可定位。
