I only see these two forward references:
In 22.1.1:
> If more than one character set can be used for a locale then the specifications can take the form
language_territory.codeset.For example, fr_BE.UTF-8 represents the French language (fr) as spoken in Belgium (BE), with
aUTF-8 character set encoding.
In 22.2.2:
> Also, a collation is tied to a character set encoding (see Section 22.3). The same collation name may exist for
differentencodings.
To me, it feels natural to discuss locales and collations first. They
are a higher level feature, they affect query results and there's new
syntax for collations. Encoding is just an implementation detail, you
just have to set client and server encodings correctly to match your
locale and the OS or application.
