Hi,
The width return by <wx.lib.graphics>.GetTextExtent(text) is not same
if you calculate the width of individual characters and sum it.
Note:
For char (" "), the width returned by GetTextExtent is only 1 unit.
The demo app is attached.

The width in GetTextExtent is calculated using the GDI+ method MeasureString. (See Graphics.MeasureString(const WCHAR*, INT, const Font*, const RectF, const StringFormat*, RectF*, INT*, INT*) method (Windows) | Microsoft Learn) I don't see anything in the wx code that would make any difference if it's a single character or the whole string, so it may be an issue with MeasureString. In any case, opening a ticket for this on wxTrac will get it in front of the person who knows more about this, perhaps he knows something about it.
