Can user-words file have punctuation? Should it have or not?

[Mark]

Hello,

I use Tesseract 3.04 on Ubuntu 12.04.

I know the words of all the papers I need to scan and I'm gonna put all of them in the user-words file but many of them are included in brackets "()" or have "-" and I also have words like these:

Anti-HAV

(Angoron)

AMH/MIS

Aντισ.Εναντι

(B-HCG)

C1

+CD56-NK

DHEA’S

HPL(

MTHFR-G20210-FV-LEIDEN

Resistance(VLEIDEN)

(TIB.C)

V(H1299R(R2))

β-FIBRINOGEN(-455G-A)

Pallidum)

ΤΟΞΟΠΛΑΣΜΑ(Τ.gondii)-ΑΝΙΧΝΕΥΣΗ

μgr/dl

Women"

Should I clean these words from punctuation or should I leave them like this? I am only gonna find these words with this exact punctuation.

Are all of the examples above legit to be put in the user-words file?

Also because I need to scan papers with English and Greek, I'm using parameter " -l eng+ell " so I also put greek words in my eng.user-words file. Is that ok?
