Hi Caden/Nate,
This patch aims to make the terminal output character set to be expected as https://github.com/tianocore/tianocore.github.io/wiki/Tasks-Terminal-driver-improvements.
It is better to add this info to the commit message. Because of the commit message length limitation, I would suggest to file a Bugzilla and attach above link.
For the poor man's line drawing, our code is using '\' and '/' instead of '+'. Should we change it to match the table?
Caden,
The patch thru email is not separated for every lines, it mixed up. So it is hard to give comment thru email. So I give my comments thru https://github.com/ZhichaoGao/edk2/commit/b9a47188d7228a47897413ca73c265143edfec29#diff-e3ef4106fc8f77b7d4ac5679f4104281cbf9a0322606703f2a6be152960c1125R300.
Thanks,
Zhichao

Hi Zhichao,
Caden is correct that ‘\’ and ‘/’ were not removed and still work fine. I have updated the table on the wiki to reflect this.
Thanks,
Nate

Subject: Re: [edk2-devel] [PATCH v2 1/1] MdeModulePkg/Console: Improve encoding of box drawing characters
I think '\' '/' works just as well if not better than '+' for the purpose they serve. I think that part of the table is an example of poor man's ascii not of all of it.
I'm not sure how to bring the other threads into this one. So here are the links to v3

Hi Caden/Nate,
This patch aims to make the terminal output character set to be expected as https://github.com/tianocore/tianocore.github.io/wiki/Tasks-Terminal-driver-improvements.
It is better to add this info to the commit message. Because of the commit message length limitation, I would suggest to file a Bugzilla and attach above link.
For the poor man's line drawing, our code is using '\' and '/' instead of '+'. Should we change it to match the table?
Caden,
The patch thru email is not separated for every lines, it mixed up. So it is hard to give comment thru email. So I give my comments thru https://github.com/ZhichaoGao/edk2/commit/b9a47188d7228a47897413ca73c265143edfec29#diff-e3ef4106fc8f77b7d4ac5679f4104281cbf9a0322606703f2a6be152960c1125R300.
Thanks,
Zhichao
