VBS implements UNICODE and ASCII encoding conversions _vbs

A, Copy a Unicode file to an ANSI file

Witoansi.vbs file:

Copy Code code as follows:

Called in batch processing:

Copy Code code as follows:

cscript witoansi.vbs [path to Unicode File][path to ANSI file]

Second, Copy a ANSI file to a Unicode file

Just make adjustments to the OpenTextFile and CreateTextFile open mode.

Iv. use of OpenTextFile and CreateTextFile

CreateTextFile method

Creates a specified file and returns a TextStream object that can be used to read or write the created file.

Copy Code code as follows:

Object. CreateTextFile (filename[, overwrite[, Unicode])

Parameters

Object

Required option. Should be the name of the FileSystemObject or Folder object.

FileName

Required option. A string expression that indicates the file to create.

Overwrite

Options available. A Boolean value that indicates whether an existing file can be overwritten. True if the file can be overwritten, or False if the file cannot be overwritten. If this value is omitted, the existing file cannot be overwritten.

Unicode

Options available. A Boolean value that indicates whether the file is created in Unicode or ASCII file format. True If the file is created in a Unicode file format, False if the file is created in an ASCII file format. If this section is omitted, the ASCII file is assumed to be created.

OpenTextFile method

Opens the specified file and returns a TextStream object that can be read, written to, or appended to the file.

Copy Code code as follows:

Object. OpenTextFile (filename[, iomode[, create[, format]])

Parameters

Object

Required option. Should be the name of the FileSystemObject object.

FileName

Required option. A string expression that indicates the name of the file to open.

IOMode

Options available. The input/output mode is one of the following three constants: Forreading,forwriting, or ForAppending.

Create

Options available. Boolean value that indicates whether a new file can be created when the specified filename does not exist. True when new files are allowed to be created, otherwise False. The default value is False.

Format

Options available. One of three tristate values that indicates in what format the file is opened. If this argument is omitted, the file is opened in ASCII format.

Set up

The IOMode parameter can be one of the following settings:

number	value	Description
ForReading	1	Open the file in read-only mode. This file cannot be written to.
ForWriting	2	Opens the file as a write-only method. This file cannot be read.
ForAppending	8	Open the file and write at the end of the file.

The format parameter can be one of the following settings:

Constants	value	Description
Tristateusedefault	-2	Open the file in the system default format.
TristateTrue	-1	Opens the file in Unicode format.
Tristatefalse	0	Opens the file in ASCII format.
