Long arrows should be a multiple of monospace
Currently, long arrows (⟵ ⟸ ⟶ ⟹) have a length about 11/12 of the monospaced characters. For laying out code (e.g., in Agda) it would be extremely helpful if their length was an exact multiple of a monospace, with 3 characters wide being the obvious choice.
Similarly, floor and ceiling brackets (⌊ ⌋ ⌈ ⌉) have a width about 5/6 of the monospaced characters. Again, it would be extremely helpful if they were the same width as all the monospaced characters.
I am writing an online textbook for which Source Code Pro would be the perfect choice, if these issues were fixed. Thank you for creating Source Code Pro, which looks beautiful!
Source Code (v2.030) does not support any of those arrow characters, so what you're getting is from a different font.
Aha! Thank you. Any chance that it could support them? Apologies for a newbie question, but how do I check which characters are in the font and which are not?
There are a few sites to test font files, among them https://wakamaifondue.com/ https://fontdrop.info
That said, it is difficult to support double-or triple-width characters in a true monospaced font. If not all glyphs have the same width, some environments won’t recognize the font as a monospaced font anymore.
Thank you to miguelsousa and frankrolf for the additional explanations.

Certain characters (Emoji, CJK Kanji, some grapheme clusters, and others) are expected to be double-width in an otherwise monospace context. Ideally one would like to have monospace full-width (double-width) fonts that are designed to be used along with a matching monospace font.
