Hi Salma,
DrawHTMLText supports only a small subset of the HTML-tags. Here you can see what's supported: https://www.debenu.com/docs/pdf_library_reference/AppendixA.php Here's a reference looking a bit different from your three samples: https://graphemica.com/%C2%B1 Where you have an eye on: Your used font is a unicode-font? How can you replace/produce the relevant sign programmatically... You can insert the sign via keyboard with the Alt-key and ascii-code 0177. So perhaps with your development environment you have syntax like chr or char... |

it's not MY QPL ;-)
It's a user website here - not a publisher page. |

Hi,
what you simply want is drawing unicode and that's not a problem with the drawing functionalities of QuickPDF. I think you know the online reference with all helping documents... If you won't succeed you can try the search function here on the page (all forums, any date, ...) with unicode , utf8 or utf as a part of the topic: http://www.quickpdf.org/forum/search_form.asp?FID=15 Edited by Ingo - 01 Feb 19 at 11:10AM |

I am able to output the ± character using DrawHTMLText. I cannot include all our code, and I do not have time to create and test a simple example to post here, but in outline our software has the following steps: s := '1234 ± 5678'; id := qp.AddTrueTypeSubsettedFont('Tahoma', 's', 0); qp.SetHTMLNormalFont('Default', id); qp.DrawHTMLText(L + xoffset, T + yoffset, W, s); The above is incomplete, untested and omits all error checking, but may help you get started. If you are not using Delphi then you will of course need to adapt this for your own development environment.
