Vertical layout: replacement of horizontal with vertical Unicode glyphs

[ronaldtse]

As described in Unicode TR50:

• https://www.unicode.org/reports/tr50/tr50-28.html

Some Unicode glyphs are meant only for horizontal text, and they have their corresponding glyphs in vertical text. However, Unicode depends on the fonts to implement these "new vertical glyphs" that fonts won't always have.

The glyph conversion table is provided here:

This conversion can only be realized in:

• Renderers for Metanorma Presentation XML (i.e. isodoc, PDF, Firelight)

In any case, the table is provided in Table 2.
