Bug#508497: text rendering fails on some documents

[Bdale Garbee]

Package: evince
Version: 2.22.2-4

I've stumbled over various rendering problems with evince before, and mostly
just lived with them.  One such example is the data sheet for the Linear
Technologies LTC1682 charge pump regulator IC, in which the text labels on
the schematic at the bottom of page one render some weird glyph instead of
the expected symbol for 'micro'.  Both xpdf and acroread get it right:

133,P1747,D1952

Today, however, I stumbled over a document that evince fails to render in a 
much more dramatic and devastating way, that again both xpdf and acroread 
handle just fine:

In this datasheet for a JST 2mm connector series, all of the text for 
dimensions in the mechanical drawings, and most of the dimensional text in
the tables, fails to render at all.  No visible errors or warnings, the image
is just displayed without the associated text.

On this document, xpdf streams errors like this in the invoking shell window:

	Error: Unknown character collection 'Adobe-Japan1'

However, the resulting rendering is virtually identical to the rendering from
acroread, and completely useable.
