The characters in a pictogram font cannot be accessed via the keyboard - how can I find them?

Although a font may contain Greek or Cyrillic characters, you can’t type these with the keyboard.
This is no mistake: your computer assumes that you want to type in Latin characters when a keyboard with Latin keys is connected. If you want to use characters from another font system instead, you have to make the computer think that a different keyboard is connected. To do this, you need to change a few settings:

Mac OS: Open System Preferences and click on Keyboard. Switch to the “Input Sources” tab.
In the left column, select the keyboard for your desired language and add it to your preferences using the small plus sign below the column.
Make sure to select the option “Show Input menu in menu bar”. The menu bar now displays a country flag.



Switch to the writing program and set the desired font with the foreign language characters.
Next, use the country flag icon in the menu bar to change the input source. This enables you to type the foreign characters using the Latin keyboard.



Windows:
There is a small country code displayed in the lower right near the time (for example, EN or DE). Right click on this and select “Settings …”.
In the window that opens, click on the button “Add …” and add the language/keyboard you want. Confirm with “OK”.



Switch to the writing program and set the desired font with the foreign language characters.
When you left click on the country symbol on the lower right near the time again, you can now change the input source and type foreign characters using the Latin-based keyboard.
