It was unintentional. I have re-opened it.

Though this bug report is marked “Fixed” and the release notes for Unifont 10.0.06 mention Sharada, these changes are not in Unifont 10.0.06. Is that intentional?

David,

I have incorporated your suggestions except for changing some of your original glyphs to these:

011182:0000000000000000000000000006000600000000000600060000000000000000

I drew all the Indic glyphs using unibmp2hex, which hard codes the whole Sharada range to be double-width. I could modify that in the future, but for now I am hoping not to have to modify any more programs.

When Andrew Miller wrote the unipng2hex utility, he did not copy the hard-coding that I used in unibmp2hex. I have left unipng2hex as is for now, because nobody else was working on Indic glyphs. That does leave a void though.

I have not changed any of the combining characters, so for example the visarga is still a combining character (and I made its dots thicker from what I originally had).

Thank you,

Paul Hardy

Apparently, Savane deletes non-BMP characters and everything after them. Let’s try this again.

U+111C4 SHARADA OM should look like U+1118F SHARADA LETTER O + U+11180 SHARADA SIGN CANDRABINDU.

U+111C5 SHARADA DANDA, U+111C6 SHARADA DOUBLE DANDA, and U+111C8 SHARADA SEPARATOR should not be so wide.

U+111C7 SHARADA ABBREVIATION SIGN should be higher and not so wide.

U+111C9 SHARADA SANDHI MARK should be lower, smaller, and not so wide. Its Unicode proposal shows that it is used between consonants without affecting their spacing, but it should not be a combining glyph, because it can be doubled. The glyph should have a headstroke to avoid breaking the headstroke between consonants, since Unifont uses a connected-headstroke style.

U+111CA SHARADA SIGN NUKTA and U+111CC SHARADA EXTRA SHORT VOWEL MARK should be shifted left to avoid overlapping vowel signs below.

Unlike U+A8FB DEVANAGARI HEADSTROKE, U+111DC SHARADA HEADSTROKE should join to adjacent headstrokes.

U+111DD SHARADA CONTINUATION SIGN should look more like it does in its Unicode proposal.

U+11181 SHARADA SIGN ANUSVARA and U+111CB SHARADA VOWEL MODIFIER MARK should be more to the right, to be above the vertical stem of most letters.

U+11182 SHARADA SIGN VISARGA overlaps U+111B5 SHARADA VOWEL SIGN II, so it should have a non-combining 1-cell-wide glyph. A headstroke is not required.

The foot of U+11183 SHARADA LETTER A should be a small triangle. My suggested glyph uses the triangle of U+111B6: the triangle of U+111AB I found too large. The same goes for the left foot of U+11193 SHARADA LETTER GA.

U+1118C SHARADA LETTER VOCALIC LL can look more like U+1118B SHARADA LETTER VOCALIC L: there is plenty of room so it need not be squished.

The diagonal stroke of U+1118F SHARADA LETTER O should meet the headstroke at a steeper angle.

The below-base vowels U+111B6 through U+111B9 should be shifted right and up so they meet the vertical stem of most letters.

U+111BA SHARADA VOWEL SIGN VOCALIC L and U+111BB SHARADA VOWEL SIGN VOCALIC LL overlap the bottoms of consonants.

The headstroke of U+111BF SHARADA VOWEL SIGN AU is one pixel too high.

U+111C1 SHARADA SIGN AVAGRAHA should be lower and not so wide.

U+111C2 SHARADA SIGN JIHVAMULIYA and U+111C3 SHARADA SIGN UPADHMANIYA combine with the following consonant, so they should be combining characters with x-offsets of 0. They should be one pixel higher to avoid overlapping the headstroke. The jihvamuliya should be one pixel left so its stem is directly above U+11191 SHARADA LETTER KA’s.

U+111C4 SHARADA OM should look like ⟨
