How can I replace a character with an unicode image?
Iman
How can I replace a - character in a text which comes from a data base into jasper field, with an image? The goal is as the illustration bellow:
Something like: $F{KN_Zusatzinfo_DV_Einleitungstext}.replaceAll("- ", "[\\x254]") where the x254 is ascii code for a red square.
But the above code writes the ascii code as is in the text and does not produce the image.

The correct syntax to render a unicode symbol is \uXXXX
For example this expression:
$F{listItem}.replaceAll("-", "\u2588")
Will render this
Now you like the dot to be red so we need to apply some style, lets set markup="html" on textElement and change the replace to this
$F{listItem}.replaceAll("-", "<font color=\"red\">\u2588</font>")
It will render:
Note: You need to be careful with regex in
replaceAll, I probably would us^-, hence starts with-(to avoid replacing other-in text), furthermore the normal way would be to just add a red rectangle element on each row. Also take care of font-extensions if you are exporting to pdf, so that your font is render correctly
