函数参考

FileGetEncoding

检测一个正在使用的文件的文本编码.

FileGetEncoding ( "文件句柄/文件名" [, 模式] )

参数

文件句柄/文件名 一个文件的句柄,有前面调用 FileOpen 函数返回的值. 当然,您也可以使用一个字符串文件名作为参数.
模式 [可选参数] 需要使用的 UTF8 检测模式.
1 = 检测整个文件的 UTF8 序列值 (默认)
2 = 检测文件最前面部分的 UTF8 序列值 (相当于 FileOpen 使用默认值打开)

返回值

成功: 返回与 FileOpen 函数相似的文件编码值:
0 = ANSI
32 = UTF16 小编码(Little Endian).
64 = UTF16 大编码(Big Endian).
128 = UTF8 (带有 BOM).
256 = UTF8 (没有 BOM).
失败: 返回 -1.

注意/说明

If a filename is given rather than a file handle - the file will be opened and closed during the function call.
Note: Do not mix filehandles and filenames, i.e., don't FileOpen a file and then use a filename in this function. Use either filehandles or filenames in your routines, not both!

If a file handle is used then the "mode" parameter has no effect - the mode used for FileOpen takes precedence.

示例/演示


Local $iEncoding = FileGetEncoding(@ScriptFullPath) ; Retrieve the file encoding of the running script.
If @error Then
    MsgBox(4096, "错误", "不能获取文件编码.")
Else
    MsgBox(4096, "FileGetEncoding", "The value returned was: " & $iEncoding) ; The value returned for this example should be 0 or ANSI.
EndIf
