go.text中的go iso-8859-1编码支持

I use go.text in my project https://godoc.org/code.google.com/p/go.text/encoding

I do not understand why it is missing iso-8859-1?

I know I can easily transcode it byte -> rune -> utf8 Unmarshal an ISO-8859-1 XML input in Go

But I wonder if there is some encoding in go.text that is iso-8859-1 but named differently. I know it has following names.

    ISO_8859-1:1987
    ISO-8859-1
    iso-ir-100
    ISO_8859-1
    latin1
    l1
    IBM819
    CP819
    csISOLatin1

You can use Windows1252 in place of iso-8859-1.

This character encoding is a superset of ISO 8859-1, but differs from the IANA's ISO-8859-1 by using displayable characters rather than control characters in the 80 to 9F (hex) range

http://en.wikipedia.org/wiki/Windows-1252

ISO-8859-1 assigns several control codes in this range. Windows-1252 has several characters, punctuation, arithmetic and business symbols assigned to these code points.

There is a chart with the differences here:
