[poll name=poll2 type=regular results=always chartType=bar]
* Microsoft Edge（新）
* Microsoft Edge（旧）
[/poll]
When I was trying to create the poll as above, I met with “Poll must have different options”.
After debugging, I figure out that there’s some wrong with the md5 function:
md5("Microsoft Edge（新）") = 695bf1ac483d572e5311e3bc9574616a
md5("Microsoft Edge（旧）") = 695bf1ac483d572e5311e3bc9574616a
This seems weird…
I looked through the code and found that /[\x80-\xFF]/.test(s) in L407 can’t correctly detect these Chinese strings.
I fixed this by forcing a conversion to UTF-8 “bytes” and made a PR to your official repo.
BTW, the following poll can’t be created, neither.
[poll name=poll1 type=regular results=always chartType=bar]
* 华东其他地区
* 华南其他地区
* 华北其他地区
