Thanks for the PR.

Please note that PRs must be based on the develop branch (not master).

You also might want to add some comments on what you are trying to do. (I'm guessing this is for #299?)

[ambar]

@pkra rebased!

I tried to use Puppeteer(https://github.com/ambar/puptex) before I found this workaround, do you think it's worth?

[pkra]

@ambar a fix for #299 would be great (and should have better overall performance than spinning up puppeteer/Chrome). But @dpvc will have to comment on the approach you're taking.

@pkra Thanks!

[dpvc]

@pkra, I'm OK with the change, if you want to merge it.

[pkra]

Thanks. I just have not got around to it -- the pending bug fix release needs to be wrapped up before we merge.

[pkra]

Sorry for taking so long to come back to this.

We're ok with merging as is.

(We thought about adding an option to customize widths of halfwidth forms but that can be done later.)

I'm wondering if we should generalize this using https://github.com/sindresorhus/string-width. I'll make a new issue.
