Answer 1

you could use:

https://webdemo.myscript.com/views/math/index.html

or

http://detexify.kirelabs.org/classify.html

or

https://www.mathcha.io/editor

to use the last one just write \ then choose inline-math then write \ again. you can see the drawing option and you can get the latex code.

Answer 2

With http://detexify.kirelabs.org/classify.html I get the message back that a possible suitable symbol is fint from the esint package (Extended set of integrals for Computer Modern) the bar is not horizontal but slightly upwards.
