I can sucessfully insert and display Uicode characeter 2080 to display a subscript zero

and this inserts this into the .svg file

<tspan
sodipodi:role="line"
id="tspan2995"
x="267"
y="360.36218">Subscript zero â‚€</tspan></text>

and this displays OK on all browsers.

But I want to be able to do this for C++ programs that write svg files.

This works for greek and other math characters, for example this string

&#x3B6; &#x00B1; &#x2080; &#x2081; &#x2082;&#x2083; in a string like this

<text x="350" y="40" text-anchor="middle" font-size="20" font-family="Verdana">Title with Unicode ^-&#945; &#x3A9; &#x3A6; &#x221A; &#x221E; &#x3B6; &#x00B1; &#x2080; &#x2081; &#x2082;&#x2083;</text>

and this displays as expected using Opera, IE9, Firefox, Chrom

But Inkscape shows the square 'not-printable' symbols for the subscript digits

Is this a bug or a feature that I can work around in some other way?

Paul

The subscript digits appear to be missing from the Verdana font (but are present in other link Times Roman, Arial, Lucida console).

Is this a bug or a feature? Should I submit a bug report?

Apart from trial and error, is there a way I can find out which Unicode symbols are implemented for each font?

(The need for these comes from the poor or non-implementation of text shifting to allow display of units like m sec-1 and chemcial formulae like H2O by other browsers - Inkscape is best for this).

Sorry for the late reply but maybe someone who is interested in such thing,
in windows you can open the character table from start menu>accessories>system tools>character table, where you can see all characters of every font in an organised way.
