Description

This is a following of GROOVY-6937 and GROOVY-6852.

The bug is fixed, but still, we miss a configuration flag in JsonSlurper or somewhere else, or another way to deactivate escaping to have a better serialization output in term of size.

See the sample attached. Comparing to the JSR 353 Reference Implementation, Groovy output is huge (> 4.8x). In an application requiring utf-8 encoding with a lot of traffic, this is clearly not acceptable.

As said in GROOVY-6937 and GROOVY-6852, this can be fixed by removing the condition line 370:
c > 126
in:
} else if (c < ' ' || c > 126) {
