I'm trying to output a Bengali grapheme cluster (সিং) which consists of 3 codepoints.



When I write input that text in LibreOffice Writer and use the "Noto Sans Bengali Medium" font it looks like this:


But when I output it with the following ImageMagick command it looks wrong: You need to download the Noto Sans Bengali font and extract the NotoSansBengali-Medium.ttf into your working directory for this to work.



Do you have any ideas what could be wrong? It looks like a bug to me.

What version of IM? If you build it yourself, what version of freetype?

You cannot put the glyph directly into label:. You need to type the glyph into a UTF-8 compatible text editor and then use @textfile.txt to load the glyph, assuming the font supports those glyphs.

See https://imagemagick.org/Usage/text/#unicode

Sorry, I forgot to mention this. I testet with ImageMagick 7.0.8-42 and freetype 2.9.1

No, but I can copy & paste. It works for a lot of other Unicode characters just fine and the webpage you linked suggests the same.

Even if you can not directly type unicode characters, one simple solution is to just 'copy-n-paste' the desired characters

The problem isn't that it doesn't work, but that it doesn't correctly combine the codepoints to render the correct grapheme cluster. Please take a closer look at the images in my first post. The last image was generated with ImageMagick by executing the command I mentioned.

Do you have the RAQM library installed? It is needed for complex text layout.

Thanks! It worked after installing the latest version of RAQM.
