This is hardly an error. You should try tweaking the input and the control
parameters. Tesseract recognized all the characters in the attached image,
with following configurations:
chop_enable T
segment_segcost_rating F
enable_new_segsearch 0
language_model_ngram_on 0
textord_force_make_prop_words F

The configs are borrowed from:
https://code.google.com/p/tesseract-ocr/wiki/ControlParams

I'm not familiar with Tesseract but I have a feeling that the trained data
were optimized for fonts with even stroke widths.
