these probably conflict, don't they :D

I've force-merged this PR because the ARM64 build was stuck with "Artifact ... already exists for build ...". |
This changeset makes 3 improvements: * Dotted lines now use a 2:1 ratio between gaps and dots (from 1:1). This makes the dots a lot easier to spot at small font sizes. * Dashed lines use a 1:2 ratio and a cells-size independent stride. By being cell-size independent it works more consistently with a wider variety of fonts with weird cell aspect ratios. * Curly lines are now cell-size independent as well and have a height that equals the double-underline size. This ensures that the curve isn't cut off anymore and just like with dashed lines, that it works under weird aspect ratios. Closes #16712 ## Validation Steps Performed This was tested using RenderingTests using Cascadia Mono, Consolas, Courier New, Lucida Console and MS Gothic. (cherry picked from commit 9c8058c) Service-Card-Id: 91922825 Service-Version: 1.19

Am I correct in the assumption that different styles for underlining are still not considered, well, a standard? Simply something that some terminal emulators added on their own? So, what's the proper way to use them in WT? Like, with PowerShell? |
|
A significant portion of "standards" are actually just "things that most terminals agree on" and not actually standardized. If you want to go for maximum compatibility, you should only use straight ( |

True, it's more a "standard" and not a standard, should've made that more clear. I think I found it:
Colors for underline styles seem to work as well, nice! The trick is that you need But it seems that is the case.. |
