Legacy ImageMagick Discussions Archive

Hi, I'm using ImageMagick so create a character map for rendering strings in OpenGL.

ImageMagick is producing the expected result for most of the characters I want but I do get a '?' rendered when I use an uncommon unicode character.

To generate the font table I loop through this command replacing the letter A with the input variable. The character I'm having trouble with is '⋅' (Dot operator) UNICODE 22 C5 : UTF8 E2 88 85.

Now, this is no big issue for me. I can easily handle a few manual steps to get the character I want. I'm just asking if there is a nicer way to handle this.

Any help/suggestions would be highly appreciated, thanks.

see http://www.imagemagick.org/Usage/text/#unicode

You may have to put the characters in a utf-8 compatible file (editor needs to be utf-8 compatible and file saved as utf-8), then read the file in with label:@filename

some copy and paste editors to terminals may not be utf-8 compatible

You did not specify a font, so the font may also be at issue as not having the (math ?) dot symbol.

That same link also points to methods of using bash and perl for converting unicode 16bit hexadecimal character codes into utf-8 strings.

Their many other programs and almost all languages that can also do this conversion.

Thanks for the comments, they were indeed helpful
