Hello.
I've found something strange while I type Korean letters on Joplin.
I'm using Kubuntu with Nimf input framework.

While Korean letters(consonants and vowels) are assembled, unnecessary space is inserted.
It's hard to tell, but just please watch the gif I attached.

I've been using several Electron based programs(Atom, Simplenote, Etcher, etc..), but there is no problem like this.

Thank you for reading!

Do you mean the small corner before each letter? Is it only Joplin that does this or are there any other programs that do it? I'm curious if it's a bug or some settings in the lib I'm using which should be set differently.

[nemonein]

Thank you for your response.
Yes, it's the small corner. It only appears on Joplin. I have never seen such thing before in any other program.

It might be(I'm not sure) related to Nimf(input framework). I'll try with other input system(such as Fcitx, ibus), and let you know the results.

I tested with another Input system, fcitx, but the result is same.
I hope you can find what causes this.

For the record: if I use Latin letters(English) only, there's no problem at all.

Does this issue also happen in the Ace Editor demo? https://ace.c9.io/build/kitchen-sink.html

[nemonein]

I have no idea about Ace Editor, but I tried.
Here's screen image when I tried with Google chrome in Kubuntu 17.10.

I've tested with a few browsers,

• Firefox on Kubuntu/Windows 10 : Works quite well. (I can't say "very well")
• IE on Windows 10 : Does not work. I could type Korean letters, but the result is weird.
• Edge on Windows 10 : I could not type Korean letters at all.

Ace is the editor that Joplin is using so if it's showing the bug in the kitchen sink it means there's probably not much I can do on my side. I see it's also doing it when inputting Chinese characters.

I have reported the bug there for now - ajaxorg/ace#3554

@laurent22 Thanks!

[laurent22]

That should be fixed in the latest Ace release so it will need to upgraded in Joplin - ajaxorg/ace#3554 (comment)

@laurent22
I don't think it's been fixed.
I've tried the latest one, v1.0.105 on Kubuntu 18.04, but it's still the same.

It also doesn't work in the kitchen sink? https://ace.c9.io/build/kitchen-sink.html

[nemonein]

It works good in the kitchen sink. https://ace.c9.io/build/kitchen-sink.html
On Google Chrome and Firefox, it's fine on both.
