--- Comment #5 from Justin L <jluth at mail.com> ---
Using Word 2016, loading a document with \lang1024, the language is
English(UK), and spell-checking-on-the-fly is checking for British spelling. So
LO is acting in the same manner as Word in this case.  [The problem is that LO
doesn't handle \noproof.]


>From include/i18nlangtag/lang.h
/*! use only for import/export of MS documents, number formatter maps it to
 *! LANGUAGE_SYSTEM and then to effective system language */
#define LANGUAGE_PROCESS_OR_USER_DEFAULT    LanguageType(0x0400)  //aka 1024

And of course as Phil indicated, this is what is returned by Language None:
#define LANGUAGE_NONE                       LanguageType(0x00FF)  //aka  255

DOCX:
LO exports "[None]" to DOCX uses w:lang w:val="zxx"
Microsoft doesn't really allow you to select either system default, or None as
a language. It does have a flag to disable spell checking on a character run
(w:noProof). However, LO does not import that.
    case NS_ooxml::LN_EG_RPrBase_noProof: // no grammar and spell checking,
unsupported

Since MS doesn't seem to have a direct corollary to LO's Language:None, it
makes sense to "invent" a language (zxx) or a number (255) so that LO can
round-trip its own settings.
