Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
Press ESC to get the coordinates of the marked region.
If you have any improvements, please post it here.
 
Tested on Win10 x64 only.
 

Ciao,
This example reproduces the problem I encounter when sending a post request to an echo server.
Instead of being sent as text utf8, the data is transmitted base64 encoded.
Example:
- json String: '{"firstName":"Jonathan","lastName":"Freeman","loginCount":4,"active": "yes","text":"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi vel volutpat nunc. Maecenas id tempus mi. Morbi ipsum enim, ultricies ac augue sit amet, ullamcorper finibus ex. Vestibulum vel posuere nibh, nec faucibus eros. Nam malesuada non lacus a suscipit. Nulla rhoncus tempus mi quis placerat. Curabitur commodo tincidunt justo quis sollicitudin."}'

How can I go about transmitting data in text format utf8?
Thanks in advance for the help.
In the zip file:
- CurlJsonPost.au3: this script
- Curl.au3: UDF by Ward (thank you!)
- data.json: json srting for command line test
 
Note: using Curl.exe with json string saved in a file (utf8 encoded) named data.json, works perfectly
To try with the command line tool:
- save data.json in curl\bin directory
- open cmd.exe and cd to curl\bin directory
- Enter the following command:
curl -H "Content-Type: application/json" --data @data.json https://httpbin.org/post
 
#Include "Curl.au3" Global $_cURL_OutputBuffer Local $sJson = '{"firstName":"Jonathan","lastName":"Freeman","loginCount":4,"active": "yes","text":"Lorem ipsum dolor sit amet, consectetur adipiscing elit.
