**Environment (please complete the following information):**
 - OS: [e.g. linux, windows, macosx]
 - Database: [e.g. postgres, mysql, sqlite]
-  Database driver: [e.g. pq, pgx]
 - Jet version [e.g. 2.6.0 or branch name]

**Code snippet**

Generated Code:

```go
const (
	TaskType_S3:init TaskType = "S3:INIT"
	TaskType_Pcap:merge TaskType = "PCAP:MERGE"
	TaskType_Ctrl:submit TaskType = "CTRL:SUBMIT"
	TaskType_Ctrl:stop TaskType = "CTRL:STOP"
)

Obviously this fails as it's invalid Go syntax.

Expected behavior The code to actually generate without errors.

You can customize the generator, and replace : character with a character of your choosing. https://github.com/go-jet/jet/wiki/Generator#generator-customization

I'm assuming that the only way to do this, is if you invoke the Generator from code?

I've made a quick fix for this bug on bug290 branch. Special characters are removed from go identifiers.

[safaci2000]

Sounds good, thank you!

I've changed my mind on this one. There were couple of bugs opened before for similar invalid character issues. To prevent any additional bugs from opening, I've made a change on master that does not remove but replaces all invalid ascii characters with the description. So in your case, it would be S3ColonInit for S3:Init enum value.

[safaci2000]

That seems like a perfectly reasonable change. Thanks for the update.

Fixed in Release v2.11.0.
