Everything on my system (that needs it) supports UTF-8 just fine.
That's all nice when you want output... But what if you want easy input ?
At the moment the only non-ASCII chars I can easily type are chars like é by using AtlGr.
But for chars like ₂ ² ≈ √ π 😀 at the moment I have to:
- Open a browser
- Surf to https://www.utf8icons.com or a similar site
- Click, type and search a lot on the site to get to a page that contains the symbol i want
- Copy it
- Paste it in the program where I need it
- (Optionally) close the browser
What I'm looking for is a program that can do something like this:
- Run in the background in a modern desktop environment (in my case Cinnamon)
- Jump to the foreground to show a whole list of reasonably popular UTF-8 symbols after pressing something like F1
- Let me click a symbol after which it will be sent to the program I was last using as if it was a keypress
- Give me the option to configure it to either stay visible after this "fake keypress" or jump back to background
In short: Are there virtual keyboard programs with support for non-ASCII UTF-8 ?
Actually... I am already happy with any method that improves mine.
Edit: For others ending up here and don't want to read all the answers themselves (or add a answer that's already given):
These are the options already mentioned + links to the answers + pro's and contra's.
Feel free to add extra solutions below (after providing them as detailed answer):
ibus(usually with CtrlShiftE) → Can't get it to work on Cinnamon
onboard→ pro: Seems to do everything I need + has support for snippets, con: Only (by default) included non-latin layout is for math, other layouts with popular UTF-8 chars have to be created manually
gucharmap→ pro: Lots of chars and easy to search con: Doesn't easily jump between foreground/background (can probably be handled with a workaround in Cinnamon itself)
kcharselect→ Same pro/con as
- Solutions from the programs themselves (e.g. Ctrl. for a couple of them) → pro: Ideal for that exact program con: Most programs, including the ones where it's needed the most, don't have one + it's not uniform
- https://www.unicodeit.net/ → pro: Good for long math formula's. con: Same problem as the one I originally stated + useless for non-math symbols
- Keyboard with extra symbols → pro: Easy con: Small amount of chars + extra keyboard needed for each system
- Shortcuts for the most used chars with
xcompose→ pro: Easy con: Depending on your memory (as human, not as computer) it only works for a limited amount of chars
- HTML entities to compose - pro/con: Too much of each, see answer
- Use CtrlShiftU, Hexcode,Space: pro/con: Same as above
