Overrides (#1)

Hi Jirimutu,

I think my definition of "over-ride" is a bit narrower than yours. My definition of "override" may be what others are referring to as the toggle. In other words, in my definition, the override is confined to the shaping of two glyphs where the glyphs can be switched/toggled back and forth between the default and a variant by the use of one variation selector. In that light, my algorithm deals with just the two glyphs, a context, and one variation selector.

I have modified the pseudo-code to match your inputs for the condition. Please check it and get back to me. Husele, Kamal, Badral, can you give comments on how you handle this shaping phenomena in your fonts?

I am sending the file with just Override #1 checked so that we can keep the discussion going. Working on #2 now. Let's keep the comments going ...

Thanks,
Greg

Hi Greg and Richard,

I have commented to your OverRides2.pdf with Red lines.
Please check if it is ok to modify the rule like this ?
I fell the original one could not cover all of the cases, And comment on it with my suggestion.

Thanks and Best Regards,

PS. All of the glyph selection is based on current NP column definition in the attached file.

Hi Richard, 

Attached please find the rules for the four over-rides.
I did this a bit fast, everyone please look over carefully to see if I made a mistake.

Thanks,
Greg

Looking at Greg's list of data sets (DS...) in his post of Saturday 8th August ('Mongolian Variation Sequences Missing from Unicode 8.00 Code Chart', http://lists.w3.org/Archives/Public/public-i18n-mongolian/2015JulSep/0248.ht

), we are missing two important items:

1) A reference scheme for rendering.  I offer one in the attachment rendering_framework.odt.

2) The rules for contextual forms that may be overridden by variation selectors.  Without these rules, we do not know whether we have an adequate set of variation selectors for rendering connected text.

I am trying to identify the contextual rules, though I am not the best person for the job.  NNBSP has me worried.  Do we need to identify suffix rules for every language that might conceivably be written in the Mongolian script with separated suffixes?

Richard.
