Question

I have a CSS file that looks fine when I open it using gedit, but when it\'s read by PHP (to merge all the CSS files into one), this CSS has the following characters prepend

Here is another good solution for the problem with BOM. These are two VBScript (.vbs) scripts.

One for finding the BOM in a file and one for KILLING the damned BOM in the file. It works pretty fine and is easy to use.

Just create a .vbs file, and paste the following code in it.

You can use the VBScript script simply by dragging and dropping the suspicious file onto the .vbs file. It will tell you if there is a BOM or not.

' Kleines Hilfsmittel, welches das BOM finden soll

 Const UTF8_BOM = ""
 Const UTF16BE_BOM = "þÿ"
 Const UTF16LE_BOM = "ÿþ"
 Const ForReading = 1
 Const ForWriting = 2
 Dim fso
 Set fso = WScript.CreateObject("Scripting.FileSystemObject")
 Dim f
 f = WScript.Arguments.Item(0)
 Dim t
 t = fso.OpenTextFile(f, ForReading).ReadAll
 If Left(t, 3) = UTF8_BOM Then
     MsgBox "UTF-8-BOM detected!"
 ElseIf Left(t, 2) = UTF16BE_BOM Then
     MsgBox "UTF-16-BOM (Big Endian) detected!"
 ElseIf Left(t, 2) = UTF16LE_BOM Then
     MsgBox "UTF-16-BOM (Little Endian) detected!"
 Else
     MsgBox "No BOM detected!"
 End If

If it tells you there is BOM, go and create the second .vbs file with the following code and drag the suspicios file onto the .vbs file.

Dim fso

Dim f
f = WScript.Arguments.Item(0)
Dim t
t = fso.OpenTextFile(f, ForReading).ReadAll
If Left(t, 3) = UTF8_BOM Then
    fso.OpenTextFile(f, ForWriting).Write (Mid(t, 4))
    MsgBox "BOM gelöscht!"
Else
    MsgBox "Kein UTF-8-BOM vorhanden!"
End If
