Mon 29 Jan 2018 06:02:46 PM UTC, comment #4: I think this is now fixed with the switch to the Adobe hinting engine. I managed to extract the Times New Roman font from Adobe Reader 5.0.5 (er____.pfb, "TimesNewRomanPSMT 001.002") and found it does indeed look like the one used in the original report. With the old Type1 hinting engine the 'e' has the problem described; with the Adobe engine the 'e' looks almost exactly like the 'good' examples in the attached pngs. The biggest difference between the new Adobe engine and the examples in the attached pngs is that that the old engines were much more aggressive about snapping stems to pixels (both horizontal and vertical).

The FreeType Type 1 hinter has a slight problem with the font "Times New Roman" (TNR.PFB). This font is shipped with OS/2 and apparently with the Linux version of Abobe Acrobat Reader v5.
