Request for segmentation example #113

Open fantasai opened 4 years ago

fantasai commented 4 years ago

Reading through the Tamil Gap Analysis, it sounds like text is segmented differently for line-breaking (https://www.w3.org/TR/taml-gap/#vertical_text and https://www.w3.org/TR/taml-gap/#line_breaking), justification (https://www.w3.org/TR/taml-gap/#justification), and letter-spacing (https://www.w3.org/TR/taml-gap/#spacing).

It would be useful to put an example of the different segmentation points for different purposes on a single string in the definition of typographic character unit, similar to how this word-break example shows different breakpoints on the same string for different word-break values.

If IIP can create such an example, I would like to put it into the CSS specification.

(Also, if it is the case that letter-spacing and justification use different segmentation rules, we should be calling that out explicitly in the CSS spec.)

It would be good to add such examples also to https://www.w3.org/TR/ilreq-taml/#h_lines_and_paragraphs

I have some material of my own containing examples which i'm more than happy to donate, if i can get some corroboration for the information it contains. See https://r12a.github.io/scripts/tamil/ta#justification
