FileEncoding PowerScript function

Description

Checks the encoding of the specified file.

Syntax

<span>FileEncoding</span> ( <span>filename </span>)

1	<span>FileEncoding</span> ( <span>filename </span>)

Argument	Description
filename	The name of the file you want to test for encoding type

Return Values

A value of the enumerated datatype Encoding. Values are:

EncodingANSI!
EncodingUTF8!
EncodingUTF16LE!
EncodingUTF16BE!

If filename does not exist, returns null.

Usage

Use this function to determine the encoding used in an external
file before attempting to use it in a PowerBuilder application.

Examples

The following example opens a file in stream mode
and tests to determine whether it uses ANSI encoding. If it does,
it reads data from the file into a blob and uses the String function
to convert the blob to a Unicode string:

long ll_filenum<br>integer li_bytes<br>string ls_unicode<br>blob  lb_ansi<br>encoding eRet<br> <br>ll_filenum = FileOpen("employee.dat",StreamMode!,<br>&#160;&#160;&#160;Read!, LockWrite!, Replace!)<br> <br>// test the file's encoding<br>eRet = FileEncoding("employee.dat")<br> <br>if eRet = EncodingANSI! then<br>&#160;&#160;&#160;li_ bytes = FileReadEx(ll_filenum, lb_ansi)<br>&#160;&#160;&#160;ls_unicode = string(lb_ansi, EncodingANSI!)<br>else <br>&#160;&#160;&#160;li_ bytes = FileReadEx(ll_filenum, ls_unicode)<br>end if<br>FileClose(ll_filenum)

long ll_filenum integer li_bytes string ls_unicode blob lb_ansi encoding eRet ll_filenum = FileOpen("employee.dat",StreamMode!,    Read!, LockWrite!, Replace!) // test the file's encoding eRet = FileEncoding("employee.dat") if eRet = EncodingANSI! then    li_ bytes = FileReadEx(ll_filenum, lb_ansi)    ls_unicode = string(lb_ansi, EncodingANSI!) else    li_ bytes = FileReadEx(ll_filenum, ls_unicode) end if FileClose(ll_filenum)
