Found the issue!

As always, with these types of problems, it was some minor annoyance that was causing it - a carriage return/line feed in the test.txt file after the string.

If I do a wc -c on the file it would give me 16 instead of 14 (2 extra for the CRLF).

Thanks for your help!

I've changed my code to use the var1=${var1}123 (thanks blowtorch) notation and also the var1=$(<test.txt) (thanks macosta) notation, which looks cleaner.

__________________________________________________________________________________________________________________________________________________

NAME
concat - Join lists together SYNOPSIS
concat ?arg arg ...? _________________________________________________________________ DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args are supplied, the result is an empty string. EXAMPLES
Although concat will concatenate lists (so the command: concat a b {c d e} {f {g h}} will return "a b c d e f {g h}" as its result), it will also concatenate things that are not lists, and hence the command: concat " a b {c " d " e} f" will return "a b {c d e} f" as its result. Note that the concatenation does not remove spaces from the middle of its arguments, so the command: concat "a b c" { d e f } will return "a b c d e f" (i.e. with three spaces between the a, the b and the c).
