How can I add overlined label text using html markup?

0 votes

I'm running the Linux version of yEd. Using FreeSans font, I have attempted to add label text to an arrow line as follows:

<html><span style="text-decoration: overline">Label</span></html>

This results in no overline being added to the text "Label". If I add underline or line-through in the same manner, then the appropriate text decoration is applied as expected:

<html><span style="text-decoration: line-through">Label</span></html>

Any ideas of why only the overline decoration would fail to do anything?

yEd leverages the Java platform's support for HTML. Unfortunately, Java implements only HTML 3.2 with limited CSS support.

Ok, thanks for the quick response! I did find a workaround where I'm using the Unicode combining overline character (U+0305) to overline each character of my label individually. It's not a contiguous overline but looks good enough (and better than adding a hash to indicate an electrical signal is asserted low in my diagram). e.g. <html>S&#x0305S&#x0305</html>
