There are practical reasons, esp when working with Unicode web pages.
Unicode encodes characters, sometimes these characters can be
represented by variant glyphs in different languages, making it
imporatnt to use different fonts for different languages.
Many users do not change the default fonts that their web browser uses.
If I was creating a web page in certain African languages, with the
character "Ŋ" (U+014A). I would not wnat to use the Times New Roman
font, since it uses the wrong glyph variant for many African languages.
If I was creating a page in the Yolngu-matha languages on the other hand
, I'd want to use a font that used the Sami variant (ie like Times New
Roman)
It becomes more problematic with Han Unification, where Chinese,
Japanese or Korean may use the same codepoint but use glyph variants.
For intsnace you're prepaing a web page in Japanese, and want to include
the Chinese names using the Chinese glyphs rather than the Japanese gylphs.
Syriac web pages are even more dependant on fonts. There are three
scripts (Estrangelo, Serto (West Syriac), and East Syriac), sharing the
same unicode block. If you need a particular script then it is necessary
to use an appropriate font.
Simarily, with the Arabic script there are two main style (Naskh and
Nastaliq). Most unicode fonts are Naskh, but as Nastaliq OpenType fonts
become available, it will possible to specific an appropraite font for
an appropraite language. For instance Naskh fonts for Arabic, or
Nastaliq fonts for Persian, Urdu, etc. Depending on typographic
preferences for different languages.
There are cases when for different languages, different fonts are
appropriate.
