调研方向
审查针对 U+25E2–U+25E5 请求的更改，以及 issue 中描述的拟议“legacy computing”字形扩展。将请求的连接行为和全高行为与现有字形的含义进行比较，并确定所需的字体制作工作流；当指定的三角形和扩展能够渲染为没有间隙的连续块图形元素时，即视为完成。

描述
Greetings and thank you for the Source Code Pro font. It is very good and is used as default monospace in many linux distributions (e.g. Fedora).
Monospace fonts are also used for terminal-based GUIs using text block glyphs such as:
█ ▊ ▋ ▌ ▍ ▎ ▏ ▐ ▕ ▁ ▂ ▃ ▄ ▅ ▆ ▇ ▀ ▬ ░ ▒ ▓ ▔ ▘ ▝ ▖ ▗ ▟ ▙ ▜ ▛ ▚ ▞ ◢ ◣◥ ◤
We notice that most font designers have chosen to make the triangles non-connecting (full height, width).
U+25E2 ◢ e2 97 a2 BLACK LOWER RIGHT TRIANGLE
U+25E3 ◣ e2 97 a3 BLACK LOWER LEFT TRIANGLE
U+25E4 ◤ e2 97 a4 BLACK UPPER LEFT TRIANGLE
U+25E5 ◥ e2 97 a5 BLACK UPPER RIGHT TRIANGLE
This precludes their use as a block-graphic element
One font implements full-height 25E2-25E5, namely unscii http://viznut.fi/unscii/ It properly renders classic PETSCII art. (I was a PETSCII artist in the 80s)
In discussions about inclusion of full-height triangles for this purpose, the unicode consortium rejected inclusion of full-height TRIANGLES in the "legacy computing" extension. Their argument was that they were pre-existing in 25E2-25E5 and that unicode does not specify a glyph's particular representation in a font, merely the MEANING.
This is obviously flawed when applied to legacy computing; the MEANING of legacy terminal-graphic characters is only achieved by being connecting elements, having full-height and width. We note for example that these have dedicated glyphs despite both being 'blocks:
U+2588 █ FULL BLOCK
U+2580 ▀ UPPER HALF BLOCK
Rejection of full-height triangles means terminal-based utilities and art can not make use of diagonal elements. We should be able to draw a diamond, for example, without space between rows.

◥◤
Despite being an 'old' tradition, text art continues to thrive to this day, and lacking full-height diagonals makes rendering historic works of computer art impossible, as well as denying us the ability to draw diagonal elements..
Would you consider revising Source Code Pro U25E2-U25E5 to use full height triangles, as well as including the 'legacy computing' glyph extensions?
