Do not use non-ASCII characters as identifiers – not all your tools support them well enough

For a very long time I’ve discouraged people from using non-ASCII characters in identifiers. It still holds.

In the past, transliterations messed things up. Even with increased support for Unicode, tools still screw non-ASCII characters up.

Delphi is not alone in this (the most important one is the DFM view as text support), see this report: [RSP-16767] Viewing a form as text fails with non ascii control or event names – Embarcadero Technologies (you need an account for this, but the report is visible for anyone):

Viewing a form as text fails with non ascii control or event names Comment

Steps:

1. create a new VCL forms application
2. drop a label onto the form
3. change the name of that label to lblÜberfall (note the U-umlaut)
4. switch to view as text

• exp: DFM content shown as text
• act: first line is shown incorrectly (see screenhsot)
