Search can't find strings with small spaces?

[Pstoppani]

In this file http://dl.dropbox.com/u/39382628/test2.pdf, the word "test" is not found, even though the file contains just two words and they are both "test".

It seems that there are some spaces between some of the characters in the array passed to the TJ handler . These spaces cause the Scanner to reset its stringDetector which prevents it from finding the complete string.

Here is what I'm seeing:

Interesting. I'll check it out. Thanks for the sample file.

My naive (just barely into the PDF spec :) fix:

"

• (CGFloat)widthOfCharacter:(unichar)character withFontSize:(CGFloat)fontSize
  {
  NSNumber *key = [NSNumber numberWithInt:character];
  NSNumber *numWidth = [self.widths objectForKey:key];
  float width = 0.;

  if (numWidth)
  {
  width = [numWidth floatValue];
  }
  else if (self.fontDescriptor.missingWidth > 0)
  {
  width = self.fontDescriptor.missingWidth;
  }
  else if (self.fontDescriptor.averageWidth > 0)
  {
  width = self.fontDescriptor.averageWidth;
  }
  else if (self.fontDescriptor.maxWidth > 0)
  {
  width = self.fontDescriptor.maxWidth;
  }

  return width * fontSize;
  }
  "

Here is a real world test file: http://dl.dropbox.com/u/8069980/neuAnnotate%20Guide.pdf
