"""
Test handling of the private typecodes:
    _C_NSBOOL, _C_CHAR_AS_INT, _C_CHAR_AS_TEXT and _C_UNICHAR

These typecodes don't actually exists in the ObjC runtime but
are private to PyObjC. We use these to simplify the bridge code
while at the same time getting a higher fidelity bridge.

These tests ensure that private type codes don't leak into the Objective-C runtime.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
