Some letters overlap using TJ

Question

I've a basic example from a PDF i'm editing.

The code

 /P <</MCID 0>> BDC q

Q    

works prefectly, producing "name" without quotes when I open the pdf.

Sadly, if I change the n with a c, something happens:

Same thing happen if i write [(N)4(a)4(m)4(e)] TJ (capital N) or with [\(Name)] TJ What am I doing wrong?

Answer 1

Perhaps your font is subset, and so does not have a glyph for c. Your PDF viewer may be substituting a glyph from another standard font, but obeying the given metadata width for the c glyph in the font dictionary for your subset font, which will be 0 for a missing glyph. Hence the overwriting.

Edit: this should have been a comment, not an answer. Sorry.
