Does anyone have a good Proper Case algorithm

Question

Does anyone have a trusted Proper Case or PCase algorithm (similar to a UCase or Upper)? I\'m looking for something that takes a value such as \"GEORGE BURDELL\"

Answer 1

There's also this neat Perl script for title-casing text.

http://daringfireball.net/2008/08/title_case_update

#!/usr/bin/perl

#     This filter changes all words to Title Caps, and attempts to be clever
# about *un*capitalizing small words like a/an/the in the input.
#
# The list of "small words" which are not capped comes from
# the New York Times Manual of Style, plus 'vs' and 'v'.

      ( $small_re ) \b           # ... followed by small word
  }{$1\u\L$2}xig;

  s{

      (?= [[:punct:]]* \Z   # ... at the end of the title...
      |   ['"’”)\]] [ ] )   # ... or of an inserted subphrase?
  }{\u\L$1}xig;

  # Exceptions for small words in hyphenated compound words
  ## e.g. "in-flight" -> In-Flight
  s{
      \b
      (? "Stand-In" (Stand is already capped at this point)
  s{
      \b
      (?

But it sounds like by proper case you mean.. for people's names only.
