Unicode Text Printing

Text printing now generates UTF-8 report files.

Overview

Text output files are now encoded using UTF-8.

Test Plan:

Bugs:

1. Reports do not display. The titlebar has the correct number of pages, but the first page says "No lines output" (or whatever the default message is). Paging forward displays 'Page is Blank or Beyond end of report" * FIXED * not sure when, but this problem does not occur using April 24th engine.
2. Unicode characters in reports do not display properly when using default viewers. Need to know what program on PC, Mac and Linux should be used to view the report and how to tell Appx which viewer to use. Tried overriding the default viewer by setting txtReportViewer to '/Applications/gedit.app', but then nothing opened on my desktop. Setting it to 'notepad.exe' on a Windows desktop worked ok.
3. Report Headings and other data are truncated. Run the Printers list in System Administration. Notice the page number on the right is truncated to just 'Pa' and the date on the left only includes the month ('11/'). This happens on both text and pdf reports.
