Hi All,

Has anyone else noticed that some of the label symbols don't work at all font sizes? Many of the symbols only work for the (almost illegible) 0 size. As far as I can tell this is a problem with Qt's rendering, and not with Kst. We might want to make some workarounds for popular symbols, however. E.g. I sometimes want to use capital Delta in fonts greater than 0, but the currently used character (0x394) doesn't work. I suggest we use the difference symbol (0x2206) as a substitute, it looks fairly similar. Lowercase \mu is the same story, but I don't know of any similar symbols.

I think it would also be good to be able to specify a unicode character directly in the label text. Here's a proposed patch, which introduces a new \char{} command. E.g. \char{0x2206} or \char{8710} would display the difference symbol.

Duncan.

The bug:

I don't see this: \mu and \Delta seem to work at all sizes on my machine.
What font are you using?  What QT are you using?

The Feature:
I like the idea.
We want to make sure it is done in a standard way. Does latex have such a
concept?  If so, how is it done there?  Is \char{} used for this anywhere
else?

I think this is related to the font or font libraries, not Qt
specifically.  (I haven't seen it happen here.)

Ok- I'm using Luxi Sans (my default, I think)
Qt: 3.3.7
KDE: 3.5.5-0.2.fc5 Fedora-Core

I can't get \mu or \Delta using my other fonts either, with the exception of 'fixed' (which doesn't really count.)

As for a standard unicode escape, the nearest that I can find for latex is \unichar{}, which is used by the UCS package. Another common thing is to use &#;. I think I prefer \unichar{}.
