414950 - Adobe Type-1 Fonts (e.g. Helvetica) Appear Scrambled (Wrong Glyphs)

Status: RESOLVED DUPLICATE of bug 396315

(Core :: Graphics, defect)

Description

[Jim Lekas]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b3pre) Gecko/2008013004 Minefield/3.0b3pre

Any page using Type 1 fonts shows text as gibberish - the wrong glyphs are displayed. For example, the characters 0123456789 produce the glyphs for OPQRSTUVWX.  Examining the page source shows that the right character codes are present in the text; only the display is wrong.

Non-Type1 fonts on the same page look fine.
The Type-1 fonts, e.g. Helvetica and are installed on my local machine.  The fonts work fine in Microsoft Word, OpenOffice 2.3 and in Firefox 2.0.0.11.

Reproducible: Always

Steps to Reproduce:
1. Install Type-1 fonts Helvetica and Garamond on the test machine.
2. Display a page containing text (see attached) using those fonts.
3.
Actual Results:  
The wrong characters are displayed for the text.  All characters appear to be replaced by characters having a unicode value 0x1F (31, decimal) larger than the correct value.  For instance, the numeral "0", with unicode value U+0030, appears to be replaced by the letter "O", with unicode value U+004F.

Expected Results:  
Normal display of text.

Attachment: Sample text showing problematic Type-1 font output.

The unicode values of the erroneous output characters were guessed, based on visual inspection.  I can't be sure whether I was looking an an en-dash or em-dash, for instance.
