Korean Language Output

[kjrstory]

I am a South Korean user. The application I use has Korean output.
In asciinema, it is displayed normally as follows.

However, when converting this to gif using, it is not output normally as shown below.

Is there anyone who can solve it?

From what I see all the symbols are rendered correctly but they're overlapping, there's not enough room between them. This is due to lack of support for double-width text characters. In the web player this is handled by web browser's rendering engine, while here we'd need to implement detection of such double-width chars and adjust their placement accordingly.

You may want to use the unicode-width crate to get fine rendering result.
While you don't want to analyze the designated fonts directly, I think this way is the best.
