Summary: Missing font every six page reloads of PDF image:
ATSFontFindFromContainer failed: count = 2.
Product: WebKit
Version: 523.x (Safari 3)
Platform: Macintosh
URL: data:text/html,%3Cimg%20src=%22http://www.irs.gov/pub/ir
s-pdf/fw4.pdf%22%3E
OS/Version: Mac OS X 10.5
Status: NEW
Keywords: NeedsRadar, ReviewedForRadar
Severity: Normal
Priority: P2
Component: PDF
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: ddkilzer at webkit.org
CC: mitz at webkit.org
* SUMMARY
Every 6th time the URL above is loaded (a PDF image), a font is reported
"missing" and a substitute font is used. This manifests itself a number of
ways:
- Large curly braces ("{") changing to a large dollar sign ("$")
- Bullets changing to a lowercase "c"
- Obvious font substitution on the page
* STEPS TO REPRODUCE
1. Launch Safari.
2. Open test URL:
data:text/html,%3Cimg%20src=%22http://www.irs.gov/pub/irs-pdf/fw4.pdf%22%3E
3. Reload page at least 6 times.
* RESULTS
Every 6th page reload, a font will go missing, and a replacement font will be
used to render the page. Console output when this occurs:
Wed Jan 23 13:51:19 hostname Safari[49430] <Error>: ATSFontFindFromContainer
failed: count = 2.
* REGRESSION
This occurs on both Safari 3.0.4 with original WebKit on Leopard, as well as a
local debug build of WebKit r29744.
Not tested on Tiger yet.
