If the included GDB does not work well for you, then you may try to replace it with a different version.

Environment and Unicode

All information given as is, with no gurantee for its correctness.

Cygwin builds GDB 8.3.1 and 9.2

When used with Lazarus 2.2 (and up) they provide full Unicode support for environment variables.

With older Lazarus versions Environment and Commandline params containing any char outside the #$20..#$7F range may result in wrong values.

Modified GDB 9.2

This is specially modified build. Wh that supports When used with Lazarus 2.2 (and up) it provide full Unicode support for environment variables.

With older Lazarus versions Environment and Commandline params containing any char outside the #$20..#$7F range may result in wrong values.

GDB 7.3.5

While it has no support for Unicode, it was modified to leave environment untouched. Therefore it was not possible to change the environment via "Run Parameters" settings. But any values set by the OS would be left intact.

Other GDB versions

Other GDB had no special support for unicode (env + args). The exact behaviour is not documented.
