[Texmacs-dev] Literal tab character in scheme

[Sam Liddicott]

I'm trying to use scheme to generate a literal tab character for verbatim export:

Scheme docs tell me that #\ht should represent the horizontal tab character, and that (string #\ht) should return such a string, but texmacs just returns a weird unicode character:

1. <extern|(lambda () `(concat "[" ,(string #\\A) "]"))>
The first example results in [A]

2. <extern|(lambda () `(concat "[" ,(string #\\ht) "]"))>
But the second example does not result in a TAB (ascii 9) within [ ] but rather unicode, which as two ascii characters is C2 and B8 whose html representation is &macr;

How shall I generate a literal tab character for text export?

Sam
