On the other hand, it is not possible to embed the entire UTF-8 font, as it is too big for a PDF documents and of course is useless. How to selectively embed the fonts with a few characters? My question is about the PDF code how to write it? Manual: With the aid of programs like FontForge, we can capture a custom font with selected characters, but how to point to the custom characters in the PDF document?
Automatic Preferred : Embedding the entire UTF-8 font into the PDF document, then optimizing the pdf documents with tools like pdftk to remove unnecessary characters.
Is there such tool? In order to embed less than the entire range of characters in a font you need to 'subset' the actual font data. That is, find the description of each glyph, store each description required, and then generate an appropriate framework to contain the glyph descriptions, which depends on the font type.
In general there is no such thing as a 'UTF-8' font. Fonts contain a series of instructions on how to draw a number of glyphs, and a means for indexing from a character code to find the correct glyph description. So in order to achieve your goal you will need to understand the font format you intend to use quite thoroughly PostScript type 1, type 2, CIDFont or TrueType , be able to determine which glyphs descriptions you need, extract those from the font, and then build a new font which contains just those required glyph descriptions.
This would be a lot of work. You cannot get this in your PDF:. Suggestion of solution: You need to get a Greek font, generate the font using proper encoding ISO and use iconv with the same target encoding as the one the font has been generated with.
I'd like to provide: a summary of the problem, the solution, a github project with the working code, and an online example with the expected, resultant PDF. If you use Font Forge, or some other font tool, you can scroll to the Chinese characters of the font, and see that they are blank. Google has a font Noto font that contains all languages, and it is 20mb, which is usually several factors the size of your text. So, you can see why many fonts simply won't cover every single language.
I'm using rounded-mgenplus I wanted to answer this for anyone who hasn't switched over to TFPDF for whatever reason framework integration, etc. Use a. Make sure to choose the encoding number that is correct for your language. Download the files and paste them in your current FPDF font directory. On the font itself, use iconv to convert to UTF Not sure if it will do for Greek, but I had the same issue for Brazilian Portuguese characters and my solution was to use html entities.
I had basically two cases:. For these, I first encoded it to html entities with htmlentities and then decoded them to iso See: How to convert Windows characters to values in php? It seems strange, by I solved the UTF-8 problem by adding a fake image an 1x1px jpeg to the pdf, just after the AddPage function:. I know that this question is old but I think my answer would help those who haven't found solution in other answers.
So, my problem was that I couldn't display croatian characters in my PDF. This is the example that worked for me:. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Valid UTF8 has a specific binary format. If it's a single byte UTF8 character, then it is always of form '0xxxxxxx', where 'x' is any binary digit.
If it's a two byte UTF8 character, then it's always of form 'xxxxx10xxxxxx'. Similarly for three and four byte UTF8 characters it starts with 'xxxx' and 'xxx' followed by '10xxxxxx' one less times as there are bytes. This tool will locate mistakes in the encoding and tell you where they occured.
Utf8 validator examples Click to use. Invalid UTF8. This example shows a red badge because the input UTF8 has an encoding error at byte Byte 59 indicates that there should be a two byte sequence following it but only one byte follows. This is malformed UTF8. Not all text is created equal. Some is missing bytes. Valid UTF8. This example shows a green badge because the input UTF8 is valid.
Pro tips Master online utf8 tools. You can pass input to this tool via? Here's how to type it in your browser's address bar. Click to try! FPDF will try to automatically generate metrics i. Such metrics are stored using the Python Pickle format.
TTF metric files often weigh about K, so keep that in mind if you use many TTF fonts and have disk size or memory limitations. By design, metric files are not imported as they could cause a temporary memory leak if not managed properly this could be an issue in a webserver environment with many processes or threads, so the current implementation discards metrics when FPDF objects are disposed.
