Current and suggested appearance of Lohit Devanagari SA
Description of problem:
The glyph for SA in Lohit Devanagari currently does not have the horizontal bar within the SA connected with the left part of the glyph. While on superficial reading and especially at low point sizes this is not a problem, it would be preferable to have the horizontal bar fully connected, especially when viewed at high point sizes.
This would greatly improve legibility and recognizability as SA (and not as RA + something), especially for the future development of Devanagari OCRs to parse documents printed using Lohit Devanagari.
The glyphs for half-SA and the ligated SRA should also be likewise corrected.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Lohit Devanagari font
2. Type स स्व स्र etc by selecting that font.
3. Increase the point size to a large number like 48.
The horizontal bar within the SA glyph, half-SA glyph and the SRA ligature is not connected to the left side of the glyph. This does not look good at large point sizes. It would also be difficult for Devanagari OCRs to parse this as the current appearance of स is somewhat similar to रा.
The SA glyph, half-SA glyph, SRA ligature (and any other current or future derivatives) should have the horizontal bar connected to the left side of the glyph.
I forgot to mention that since now we are shipping Lohit Marathi and other Lohit Devanagari derivatives, this should be corrected there as well. So far there is no known requirement for a particular localization of Devanagari to have the SA glyph look like something specific, and the OCR situation would be common there also.
Good catch, even Unicode shows shape with connected horizontal bar. I have committed changes in upstream, this will be available with next release.
Just noticed that even the glyph for STRA (glyph $0175) has to be corrected. That makes a total of four glyphs: SA S_half SRA and STRA.
