An application is enable by the physical fonts to get great advantage of the all present fonts. This is actually done to accomplish maximum language coverage as well as different text appearances. However, this is a tough task to create those applications which yse these physical fonts.

To bundle the physical fonts along with application makes you able to create those applications which possess same look and also the great control at those applications. However these bundled fonts are quite big in their size especially in case you want to support an application with Korean, Chinese and Japanese. Additionally, licensing issues need to be resolved.

There is a guarantee that logical fonts work anywhere. Text rendering is also possible in the languages which are localized to host operating system. Physical fonts that are used to render text usually vary b/w locales, host operating systems and different implementation. Therefore, it is not possible for an application to get the similar look everywhere.

Occasionally, range of characters which might be rendered is limited by mapping. Before 5.0, on JRE versions the latter was a bigger problem. E.g. it was possible to render the Japanese text at Japanese localized host operating system. It was not possible for any other no matter if the installation had been done of the Japanese font. Applications that were using 2D font rendering such kind of problem is quite rate for JRE version 5 as well as all other later as fonts are used and recognized for supported writing systems by the mapping mechanism, if they are installed.
