Reduced Planck Constant Lacks a Concise Braille Representation in UEB Output

[NV-Codes]

MathCAT Version

MathCAT-0.6.6 (NVDA Add-On)

Description of Issue

The reduced Planck constant, $\hbar$ (Unicode symbol ℏ), lacks a concise representation in MathCAT's UEB output. The Nemeth output, however, simply uses dot 4 before dots 1-2-5 to represent the symbol. An appropriate concise representation for the reduced Planck constant would greatly enhance the experience of reading physics formulas with the UEB technical code.

I think your idea is a good one, but I don't want to deviate from the official standard, even when that means there isn't a representation.

I have email for some people involved in the UEB standard for technical material. I'll write to them to see if they suggest something for ℏ.

As a work around for yourself, you can modify the file %AppData%\nvda\addons\MathCAT\globalPlugins\MathCAT\Rules\Braille\UEB\unicode-full.yaml and add a line for it that looks a bit like

 - "ℏ": [t: "L⠓"]              # 0x210F

The above represents the "h" part; you would need to add some characters to indicate the presence of the stroke as an overlay. Any braille should be in the Unicode braille block range.

Note: the file will be replaced when MathCAT updates, so you'll to keep making that change until there is a fix.

That makes sense, thank you!
