LaTeX errors with Greek symbols

PGvdVeen shared this problem 4 years ago
Solved

Enter in GG 5.0233 a text

\mbox{This is the coordinate x and this is the angle α}

and mark the text as LaTeX


The text is now incorrectly displayed. It breaks off after 'angle'.

The problem arises when I select a symbol but also when I use short-keys ALT-a

Many of my applets show this problem. It was not present in earlier versions like 5.0.19.

Hi, can you please post a link to one of the affected applets?

The error is only in the ggb, not in the HTML. But this brings great diffiulties in editing texts.

I confirm with 5.0.233.0 linux : ok on the web and not on the desktop version (picture joined)

Another very annoying bug is that mbox{a_1} is not correctly displayed as a with subscript 1

I tried to solve a simular problem with the Sigma sign.

The solution I found is shown in the screenshot.

I am not sure this is a stable solution, but it works for the time being.

Kind regards,

In the past \mbox{a_1} produced the underscore. Now it doesn't any longer.


A workaround is \mbox{\[u_1\]}

For some reason \[ and \] are active and useful tags :-)

The content of \mbox{} is in text mode (spaces work) so math mode features like lower index should not be supported. \[ and \] switch to math mode. The underscore behavior seems to be the same since at least GeoGebra 4.2.


The bug in the first post of this topic is relatively new, we will try to fix it.

Please do! This is a very annoying bug, resulting in huge difficulties when editing more than trivial texts.
