My language letters become to hieroglyphs in VBA. Need help.

Hi,
I have huge problem. I have workbook with vba codes with links to workbooks which consist of letters in my language ( š ę ė etc...)
And when I gave this workbook to my colleague, all my language letters (like š ę ė etc...) became to hieroglyph
Can anyone help for me?
Thank you all, and sorry for my english..

Nobody can help me?

Sorry for my missunderstanding. I ll copy codes before and after.

Private Sub CommandButton2_Click()
On Error GoTo Klaida
Workbooks.Open Filename:="\\linktoworkbook\Žaliavų sąrašas\zaliavos.xlsm"
Workbooks("zaliavos.xlsm").Sheets("mdp").Activate
Exit Sub
Klaida:
MsgBox ("Lentelė atidaryta"), vbExclamation, "Klaida"
End Sub

This code is good, but when I send it to my colleague, code becomes:

Private Sub CommandButton2_Click()
On Error GoTo Klaida
Workbooks.Open Filename:="\\\linktoworkbook\Þaliavø sàraðas\zaliavos.xlsm"
Workbooks("zaliavos.xlsm").Sheets("mdp").Activate
Exit Sub
Klaida:
MsgBox ("Lentelë atidaryta"), vbExclamation, "Klaida"
End Sub

I start to think, that our language is not installed into my colleague computer, and thats the problem.
