I am a new person.
If only the space after "[4" is a problem, I can fix it using the variable
spaceAfter (TextOutputDev.cc).

Another possibility is to store a GfxFont* array in TextWord, so that every
letter has its own font.
I tested this and it works fine, but the rest of poppler still acts as if
one word had only one font. A word would have
a "main font" and letters with individual fonts. It is not a very clean
solution, but probably better
than starting new words.
