PDFBOX : U+000A ('controlLF') is not available in this font Helvetica encoding: WinAnsiEncoding

[PROBLEM] The String you are trying to display contains a newline character.

[SOLUTION] Replace the String with a new one and remove the newline:

text = text.replace("\n", "").replace("\r", "");

The answer selected for this post works, replacing all instances of \n and \r from your string, if you know that it's a \n or \r character that's causing your problem. I've discovered that there are lots of different characters that will produce this error. Here's a sampling of those that I've found:

U+2010 ('hyphentwo') is not available in this font Helvetica encoding: WinAnsiEncoding
U+2033 ('second') is not available in this font Helvetica encoding: WinAnsiEncoding
U+00A0 ('nbspace') is not available in this font Helvetica encoding: WinAnsiEncoding
U+FFFD ('.notdef') is not available in this font Helvetica encoding: WinAnsiEncoding
U+03BC ('mugreek') is not available in this font Helvetica encoding: WinAnsiEncoding
U+039C ('Mu') is not available in this font Helvetica encoding: WinAnsiEncoding
U+2212 ('minus') is not available in this font Helvetica encoding: WinAnsiEncoding
U+0141 ('Lslash') is not available in this font Helvetica encoding: WinAnsiEncoding
U+2103 ('centigrade') is not available in this font Helvetica encoding: WinAnsiEncoding
U+25AA ('H18543') is not available in this font Helvetica encoding: WinAnsiEncoding

In my case, I've simply chosen to remove any special character that's not included in my font. I used the solution from this page:

If you'd like to retain the newline addition, i.e you indeed want your text to split and appear the later part in new line, then you can simply replace the \n with an HTML break tag, like below below .

return text.replace("\n","<br>");
