- all Unicode format controls can be found under MORE CONTROLS
- mousing over a character reveals its description as well as the code point, and its MdC notation

Extended-A is not yet supported.

There may also be a need for a new character.

Changes also incorporate general revisions that are slowly being rolled out across all pages.

Chakma orthography notes updated.
r12a.github.io/scripts/cakm...

There is still much more to understand about how the Chakma script works, but the notes have been updated to talk about simplified vs traditional orthographies, and some clarifications around onsets, finals, and consonant clusters.

Most term lists for these orthographies have also seen a significant increase in the number of terms and transcriptions.

INDIC orthography notes sections on vowels, consonants, encoding choices, and shaping have been largely rewritten for Hindi, Malayalam, Gujarati, Kashmiri (deva), Tamil, Bengali, Odia, Punjabi, Telugu, and Sinhala.

r12a.github.io/scripts/inde...

The notes can also be accessed via the Analyse Text control. When the data appears, click on the Notes to see the notes.

NEW PICKER FEATURE: In-page notes

Highlight some text, click on List Characters, then click on a character name in the popup. This will display any available notes about that character in the right half of the screen.

Try it: r12a.github.io/pickers/mlym...

NEW PICKER FEATURE: Copy list items to clipboard

When you select List Characters, each line in the list has 2 icons to the right. The first copies just the character; the second copies just the Unicode name.

Tip: In Blink/Gecko browsers this is just 1 tab key press away from the text area. Two tabs takes you to the control to input characters as escapes/code points.

NEW PICKER FEATURE: New font size slider

An extra font size slider has been added just below the bottom right of the text area. The autofocus control that used to be here can now be found as an icon to the right.

BENGALI VOWEL LIGATURES

The Bengali orthography notes section r12a.github.io/scripts/beng... now shows which Noto/System fonts support ligation for ru, rū, etc. And which browsers support associated ZWJ and ZWNJ behaviours. (It's very complicated!)

However, if the text area includes several lines of text, that icon removes the line breaks, too.

The new icon collapses spaces while retaining the line breaks.

NEW PICKER FEATURE: Collapse spaces but keep lines

Pickers make it easy to rearrange/add/delete/change combining marks by clicking on an icon to the right of the text area which adds space(s) between each character. Clicking another icon removes the spaces once the edits are complete.

NEW PICKER FEATURE: Render HTML

Pickers will now do basic rendering of simple HTML snippets. (Esp. useful for testing RTL behaviours.)

Hint: Set the direction to LTR override to manage bidi with HTML. Type the HTML. Select Render HTML from pulldown menu.

Try it: r12a.github.io/pickers/arab...

Thanks to Vinodh Rajan, the webfont used for these pages now uses a font that supports the Kashmiri vowel signs (and a lot more conjunct forms).

The input field that allows you to add characters to the text area in a picker by typing code points or escapes has been moved just below the text area, for convenience.

Just type one or more code points or escapes and hit return to add the character to the text area.

r12a.github.io/pickers/

Sharada is a major South Asian abugida used, mostly historically, in India for Sanskrit and Kashmiri, from CE 8thC – 20thC.

These resources include references to the additional Kashmiri vowel characters that will be included in Unicode 17.

NEW SCRIPT INFO: Sharada (Sanskrit/Kashmiri)

Orthography: r12a.github.io/scripts/shrd...
Picker: r12a.github.io/pickers/shrd...
Term list: r12a.github.io/scripts/shrd... (72 items)
Char notes: r12a.github.io/scripts/shrd...

Character pickers can now show the grapheme clusters in a highlighted string.

The Grapheme segmenter app has also been updated to incorporate the Unicode 15.1 segmentation rules for indic conjuncts.

Try it: r12a.github.io/pickers/beng...

For example, if you have Noto fonts installed for Arabic, try the following URLs.

r12a.github.io/pickers/arab...
r12a.github.io/pickers/arab...
r12a.github.io/pickers/arab...
r12a.github.io/pickers/arab...

NEW PICKER FEATURE
It's now possible to create a URL pointing to a picker that not only adds text to the text area, but that also applies a given font to it (as long as the receiver has the font installed.) Use underscores for spaces in the font name.
