I could not find any trace of this problem, I hope I did not give up too early. Documents using the Arial or Helvetica font which contain the "°" character followed by a space in most cases causes additional white space to be added furtheron on the same line when I convert them to PDF. Such additional white space sometime is added between two words, but often between two characters of a word so as to cause such word to be cut in two parts. The PDF files shows up correct when displayed with GSview 4.6/Ghostscript 8.14, but not in any other PDF viewer (tested with Acrobat 4, Acrobat Reader 4 and Acrobat Reader 5.1 on a PC, and with Freehand, Adobe Illustrator and the OS-X default PDF viewer on a Mac). I checked the PostScript file, and could not find anything wrong with it, but my tests with various PDF viewers cause me to belief that the problem is due to the PDF file contents, and not the viewer. For information, all viewers that I used to print the test files I created not only display the additional space, but also print it. If you want me to, I can provide you with the PostScript and PDF files of the test document I created by E-Mail or any other way that's convenient for you.
Please re-visit the bug report and attach the sample file.

Most likely the problem is caused by incorrect metrics of the degree symbol in NimbusSanL-Regu (n019003l.pfb). This happens with both v.6.0 and v.8.11 of the font. Installation of real Helvetica fixes the problem.
AFN line for NimbusSanL-Regu C -1 ; WX 606 ; N degree ; B 151 383 454 686 ; AFM line for Helvetica C -1 ; WX 400 ; N degree ; B 54 411 346 703 ;
Dear Mr. Cherepanov et al., I would not be surprised if (i) the degree symbol is not the only character for which differences between the various Helvetica font variations exist; and (ii) similar issues exist with the other fonts. Is there any tracking system/list that documents all known issues of this type? Thanks for all the help. Kind regards, Bo
There is a super bug 687297 that tracks all issues for the new font release. Although a few other problems have been reported before, this is the first report of a problem in font metrics. We really need to draw the Ghostscript fonts side by side with the corresponding Adobe fonts and fix all the significant differences.
Created attachment 704 [details] test2.zip: Contains PS and PDF files for other fonts with degree char. This ZIP file contains the PostScript and PDF files I created from a small document with some more test lines containing the degree character, using the Helvetica, Helvetica Narrow, Times and Courier fonts, all in four variations: Regular, Bold, Italic and Bold/Italic. The degree character systematically causes problems with the Helvetica font, not with any other font for as far as I could see. I created two other test documents as well locally to test the "|" and "~" characters, but did not find any problem with them.
