You can code it manually or find a function on MSDN that you can call with the system plugin...

Ok. I already wrote it by myself. May be someone needs:

!include "LogicLib.nsh"

>!include "CharToASCII.nsh"


>Function URLEncode

    Pop$0 ;param

    StrCpy$1 -1 ;init counter

    StrCpy$9 "" ; init buffer

    

NextChar:

   IntOp $1 $1 + 1

    StrCpy$2 $0 1 $1 ;get char

        

   ${If} $2 == ""

        Goto Done

    ${EndIf}

    

    ${CharToASCII} $3 $2 ; get charcode

    

   ${If} $3 == 32

        StrCpy$9 "$9+"

        Goto NextChar

    ${EndIf}

        

    ${If} $3 == 95

   ${OrIf} $3 == 45

        StrCpy$9 $9$2

        Goto NextChar

    ${EndIf}

        

    ${If} $3 >= 33

   ${AndIf} $3 <= 47

        IntFmt$4 "%X" $3

        StrCpy$9 $9%$4

        Goto NextChar

    ${EndIf}

    

    ${If} $3 >= 58

   ${AndIf} $3 <= 64

        IntFmt$4 "%X" $3

        StrCpy$9 $9%$4

        Goto NextChar

    ${EndIf}

    

    ${If} $3 >= 91

   ${AndIf} $3 <= 96

        IntFmt$4 "%X" $3

        StrCpy$9 $9%$4

        Goto NextChar

    ${EndIf}

    

    ${If} $3 >= 123

        IntFmt$4 "%X" $3

        StrCpy$9 $9%$4

        Goto NextChar

    ${EndIf}

    

    

   StrCpy $9 $9$2

    Goto NextChar

    

Done:

   Push $9

FunctionEnd

Using:


    Push "hello dolly!"

    Call URLEncode

    Pop$0 ; now $0 contains "hello+dolly%21"
