Cannot use % within an arg (template data) to the translate func

[jhart1685]

I've spent a few hours trying to figure this out, but it looks like it is not possible for an argument (/insert) on a call to i18n.T to contain a percent character.

anonymized code:

func main() {
	input := "%"
	fmt.Printf(i18n.T("<my translation ID>",
		map[string]interface{}{
			"Insert": input,
		}))
}

Output (with preceding message text removed):

%! (MISSING)

I've tried substituting % with %25 , url escaping , passing in as byte slice rather than string.

But it looks like a percent anywhere within a value (of the args template data) gets garbled.

Note - this is not a generic problem with Go template processing. The following snippet works just fine:

func main() {
	input := "%"
	formatter, _ := template.New("TestTemplate").Parse("{{ .Insert }}")
	f := bufio.NewWriter(os.Stdout)
	defer f.Flush()
	err := formatter.Execute(f, map[string]interface{}{
		"Insert": input,
	})
	if err != nil {
		panic(err)
	}
}

What does the translation for <my translation ID> look like?

I am not able to reproduce this with the information you have given me.

For example, this test passes:

func ExamplePercent() {
	i18n.ParseTranslationFileBytes("en-us.all.json", []byte(`[
{
	"id": "hello_person",
	"translation": "hello {{.Person}}"
}
]`))

	T, _ := i18n.Tfunc("en-us")
	fmt.Println(T("hello_person", map[string]interface{}{
		"Person": "%",
	}))
	// Output:
	// hello %
}

If you can write a failing test, the would be the most helpful.

Hi @nicksnyder - thanks for the quick response.
Apologies - this was user error. The difference between your test and mine was that yours wrote the output with Println(), while I used Printf() without a format. The returned string from the translate func was correct - but it got mangled by my misuse of Printf.
