How to fully display certain double width symbols

[dahewangnaliu]

I need to use SwingTerminalFrame to output some special symbols, such as "→", "●", etc. These characters are usually not fully displayed and can only be displayed halfway. And I couldn't find a font with better display effect.

I think these special characters should be classified as double width characters
