That's fine though. On Linux distributions care is usually taken to ensure fonts that cover all languages in common use today, but there is no need to cover every glyph in the standard right from the start. Some Unicode blocks eventually get a default font, some are so specialistic that you have to install a special font, but that's perfectly doable. Newer versions of distributions tend to come with updated versions of the fonts installed, so eventually support will increase.
