[support] Substr or Drupal_substr?

[richard at damon-family.org]

 The problem is that substr does not fully support strings with an utf8
encoding (it counts the multiple bytes as different characters and can thus
chop characters in two). PHP does have (in many versions) multi-byte
character functions to handle these sort of strings, but they are not
enabled by default (and I am not sure if they were generally available when
Drupal first started to use utf8). I guess the implementers of Drupal felt
is was easier to implement their own version of the functions to be m utf8
aware than to deal with the support issues of telling people how to get
these functions enabled on their system. Remember that many people are on
shared hosting systems where adding modules into PHP is not trivial, and
sometimes requires negotiating with the hosting provider to get them to
install it.

system, Drupal is too slow, and this would only add to the overhead of
processing a very simple command. Is Drupal becoming a language in it's own
right?
