== Description ==
Read Unicode Files.
The Function is very similar to the built in FileRead function.
It reads in an ASCII Unicode text files by line.
Note that multi byte characters are not read correctly and characters with more than two bytes throw the whole line if not the whole file off.

== The Function ==
<highlight-nsis>
Function "FileReadUnicode"
Pop $0 ; handle
Push $1
Push $2
Push $3
Push $4

IntOp $4 0 + 0
IntOp $3 0 + 0
StrCpy $1 ""
SetErrorLevel 0
read:
FileReadByte $0 $2
IntCmp $4 0 0 skip skip
IntCmp $2 0x0a skip 0 0
IntCmp $2 0x0d readsecondhalf 0 0
IntCmp $2 0 done 0 0
IntFmt $2 "%c" $2
StrCpy $1 "$1$2"
skip:
IntOp $4 $4 + 1
IntOp $4 $4 % 2
Goto read
readsecondhalf:
FileReadByte $0 $2
done:
Pop $4
Pop $3
Pop $2
Push $1
Exch
Pop $1
FunctionEnd
</highlight-nsis>

== Sample Code ==
<highlight-nsis>
FileOpen $R0 "c:\unicode.txt" r
IfErrors done
read:
Push $R0
Call FileReadUnicode
Pop $R1
IfErrors done
MessageBox MB_OK "$R1"
Goto read
done:
</highlight-nsis>
