Do not use AlphaNum when string contains comma

eigan · web-flow · commit 03e84852b4e8 · 2025-09-19T10:41:26.000+02:00
Using dash in this context will create a range between `+` and `.` which allows the following characters: `+`, `,`, `-`, `.`. 

The ASCII range is as follow: + (43), , (44), - (45), . (46).

Comma is not supported and will then crash in `write()`.
