Tesseract 4.1 - Using PageSegMode.SingleBlockVertText does not work

[charlesw]

The following unit test are failing in Tesseract 4.1 build (branch features\321-Tesseract-4):

• EngineTests.CanParseText_UsingMode(SingleBlockVertText,"A line of text")

Preliminary investigation indicates the problem is with tesseract itself, however yet to be confirmed (haven't yet reproduced directly using tesseract).

Completely green on tesseract, just started a project to implement it in a .Net app. When I test with Japanese and --psm 5 I get a line of text, with Japanese and --psm 6 I get a vertical line of text.
Could it be that the English data is not trained on vertical text that is causing the issue?

No idea really, just noted that the associated unit test was failing. Next thing would probably be to get an official build and test it which would indicate if the problem's in tesseract or how I built the library.
