[dein] Error generating helptags:
[dein] Vim(helptags):E670: Mix of help file encodings within a language: /Users/mhartington/.config/nvim/.dein/doc/webdevicons.txt
[dein] function dein#end[1]..dein#util#_end[39]..dein#recache_runtimepath[1]..dein#install#_recache_runtimepath[20]..<SNR>8_helptags, line 12

I've been poking around in the doc file, trying to see where the error is coming from. Seems like bad encoding is happening in nvim, but not regular vim(7.4).

I'll try to hunt it down and look for the culprit and send a PR your way.

Cheers.

Thanks and I appreciate it. Let me know if I can help but I might not be able to

@ryanoasis I have the same issue.
I don't know help file encodings details, but maybe(not tested), it caused by added ✅ icon into the doc/webdevicons.txt?
It seems have not that icon on 1bd919e.

I will test it later.

[ryanoasis]

@zchee Hey thanks

Cool thanks for the fix. Ha who would have figured that would cause such a breaking issue 😛

I actually generate the vim doc file from the readme markdown using html2vimdoc so I might need to adjust something after it builds or it will recopy that glyph and I kind of like having it on the readme 😄

for reference: https://github.com/ryanoasis/vim-devicons/wiki/Development-Workflow

Anyway I am going to tag this for the next release 👍

Hi,
I still face this issue with dein on nvim 0.1.6-72-gfe06e2a . Any pointers?

Thanks

[mhartington]

Same here. Maybe it has to do with html2vimdoc?

[ryanoasis]

@junkmechanic did you pull the latest devicons?

[junkmechanic]

hi @ryanoasis
my last pull was a few minutes before posting that comment. So, yes. :D .

Its when @mhartington mentioned that it could be an issue with html2vimdoc is when I glazed over the code. It explicitly encodes the output to utf-8 before printing it.
Speaking out of limited experience with shell redirection (and most other things for that matter), this could be an issue with how the output is being redirected to the doc file. You might want to modify the script so that one could give it an output file name that it could directly open a pointer to and dump the text.

gitter_shougo[m]        vim-devicons documentation header has multibyte characters.  It is invalid.
gitter_shougo[m]        https://github.com/ryanoasis/vim-devicons/blob/master/doc/webdevicons.txt#L1
gitter_shougo[m]        It contains multibyte hyphen character.
gitter_zyx-i[m] @Shougo I do not see hyphen there, only EN DASH. Why is this a bug in webdevicons.txt and not in Vim/Neovim?
gitter_shougo[m]        Because,

gitter_shougo[m]        It is invalid character.
gitter_shougo[m]        The new is correct.
gitter_shougo[m]        Yes, it is hard to notice.
gitter_zyx-i[m] It is not invalid. EN DASH is exactly what should be used here, HYPHEN-MINUS is not the right character in all cases where it could be used.
gitter_zyx-i[m] * Not the right in all texts read by humans.
gitter_shougo[m]        Yes, it is not invalid in English
gitter_shougo[m]        It is invalid in Vim/neovim helpfile.
gitter_zyx-i[m] Text file is for reading by humans, so it is Vim/Neovim bug if they have any problems with HYPHEN-MINUS.
gitter_zyx-i[m] I have not seen any arguments for this being not valid in a help file.
gitter_zyx-i[m] And, by the way, how Vim/Neovim could work with translated help files if they can’t handle single EN DASH?
gitter_shougo[m]        The documentation title line must not contain multibyte characters.
gitter_shougo[m]        I think it is Vim/neovim feature.

gitter_zyx-i[m] @Shougo Read `:h help-writing`. I do not see statements like “The documentation title line must not contain multibyte characters.”
gitter_shougo[m]        I think it is because the title lines are merged to "help.txt".
gitter_shougo[m]        I think it should be documented.

gitter_shougo[m]        Thirs is 4 years ago post.
gitter_shougo[m]        Some Vim contributors answered.  (No Bram's answer though)
gitter_zyx-i[m] This still looks like a bug. And people there think it is a bug.
gitter_shougo[m]        https://groups.google.com/d/msg/vim_dev/kIY3ut_smBk/vx88qMKQLb4J
gitter_shougo[m]        It is sent to vim_dev in 2008.
gitter_shougo[m]        Bram says it is feature.
gitter_shougo[m]        neovim can change the feature though.

Not sure when they intend to fix this feature/bug in neovim, but in the meantime, would it be possible to change the hyphen in the title of the doc?

[mhartington]

hey @ryanoasis, sorry to ping, but could this be reopened? Looks like it's still around, and the explanation seem to be legit.

Will try to PR.

[ryanoasis]

@mhartington Darn. Yeah sure go for it.

I did update the build notes so it doesn't accidentally make it's way back: https://github.com/ryanoasis/vim-devicons/wiki/Development-Workflow

But maybe there is another character causing issues.

Good luck

[mhartington]

Tested it out locally, it is indeed that - in the title that causes the issue

From the looks of it, just removing that and dropping the Add Icons to Your Plugins part down a line seems to be fine

Makes sense

I'd prefer to keep it as is. Maybe replace the dash – with a hyphen -. Does that also solve it?
