That reminds me of an answer on stack overflow, Changing font of PDF using iTextSharp <http://stackoverflow.com/a/15241639/1729265> ... As that solution worked "as per [the asker's] expectation," I didn't look into it. That person actually merely replaced the base font name leaving everything else untouched.

If you did the same trick and now run into this kind of problems, you most likely have not adjusted the character widths array. Therefore, the PDF viewer thinks it should display the Braille characters using the widths of the corresponding Arial characters. PDF objects representing Arial in a PDF look like this: 9 0 obj << /Type /Font/Subtype /TrueType/Name /F0/BaseFont /Arial /Encoding /WinAnsiEncoding/FirstChar 32/LastChar 255/Widths [278 278 355 556 556 889 667 190 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 584 584 584 556 1015 667 667 722 722 667 610 778 722 278 500 667 556 832 722 778 667 778 722 667 610 722 667 944 667 667 610 278 278 278 469 556 333 556 556 500 556 556 278 556 556 222 222 500 222 832 556 556 556 556 333 500 278 556 500 722 500 500 500 334 260 334 584 750 556 750 222 556 333 1000 556 556 333 1000 667 333 1000 750 610 750 750 222 222 333 333 350 556 1000 333 1000 500 333 944 750 500 667 278 333 556 556 556 556 260 556 333 736 370 556 584 333 736 552 400 549 333 333 333 576 537 278 333 333 365 556 834 834 834 610 667 667 667 667 667 667 1000 722 667 667 667 667 278 278 278 278 722 722 778 778 778 778 778 584 778 722 722 722 722 667 667 610 556 556 556 556 556 556 889 500 556 556 556 556 278 278 278 278 556 556 556 556 556 556 556 549 610 556 556 556 556 500 556 500]/FontDescriptor 13 0 R >> endobj 13 0 obj << /Type /FontDescriptor/FontName /Arial /Flags 32/FontBBox[-250 -144 2664 864]/Ascent 864/Descent -144/CapHeight 864/AvgWidth 432/MaxWidth 2664/MissingWidth 2664/StemH 78/StemV 78/ItalicAngle 0 >> endobj When changing this to Braille, it generally does not suffice to replace the name. Instead the other pieces of information you see here also should be adjusted. In your case the effects of the /Widths array are most appearant but the other entries visible here should be inspected, too. > file fully converted into Braille font but there is very less distance > between two character.so I thought if I could set a spacing between two > character, my problem would be solved. > OR > please tell me any easer way to change the all text fonts into Braille or > any selected font. I would propose you first try to replace the other relevant font information (first your widths array), too, not only the base font name. Then start dealing with text that went beyond the margins and other visual artifacts.
