The meta OpenType table allows adding a structure which describes the languages and scripts for which the font is recommended. This is an excellent tool to record ISO script and language codes for which the font is especially designed. The dlng section inside the meta table indicates for which languages and writing systems the font has been designed for.
This data can potentially be more specific than probing the fonts. For example, in the Noto CJK fonts, the ISO script codes Hans (Simplified Chinese), Hant (Traditional Chinese), Jpan (Japanese) and Kore (Korean) can be used to show which font has the preferred form.
