I am using LibreOffice Draw. I want to change the font of all brackets. Like (), {}.
My default font is Kinnari. But I want all my brackets to be Arial. How can I achieve this?
Any help is appreciable.
Once you have selected the characters to change, either use Format>Character or the formatting side pane.
If your “brackets” are the only text in the text boxes, a more comfortable procedure is to define a custom style. All you need then to do is double-click on the style name to reformat the text box (colour, border, font face, size, weight, …).
It looks like you’re using Draw to format equations. If this is the case, I suggest you use Math, the formula editor, which will give you easier control and faster result.

In case you need clarification, edit your question (not an answer which is reserved for solutions) or comment the relevant answer.
If a task requires operations like the one discussed here, Draw is definiely the wrong tool. There are no character styles, and the F&R tool (which I never used in Draw, but just now tested) seems to be next to useless.
Using a TextBox in Writer, the F&R can find single occurrences based on RegEx e.g, but Find All doesn’t work, and styles defined for the overall text ranges of the document are not available for the content of TextBox objects.
Avoid TextBox objects wherever possible!
To support F&R for editing and formatting of TextRange objects inside TextBox Objects you would need a system of rather complicated “macros”. (Yes. It’s feasible, but would imo require to work with temporary helper documents.)
Appended: For other shape types accepting text it should be the same.
