AutoHotkey's Loop (read file contents) issues related to "+" symbol - loops

Question

Referring to Loop (read file contents), a quite strange thing happens every time I use a code like this one to run a script:
^+k::
{
Gosub, MySub
}
Return
MySub:
{
Send, +{Enter}
Loop, read, C:\MyFile.txt
{
temp = %A_LoopReadLine%
Send, %temp%
Send, +{Enter}
}
}
Return
MyFile.txt is a simple text file where sometimes the "plus" symbol (+) is used together with normal letters and numbers.
Despite of this, however, what I see if I run the hotkey on an empty text file, either a Notepad or Microsoft Word blank sheet, is that every + is replaced by an underscore (_), an exclamation mark (!) or a question mark (?). I've seen an occurrence with a dollar symbol ($) replacement, too.
I tried to debug it printing on screen a message box with
MsgBox, %temp%
before sending text and it shows the original content of MyFile.txt perfectly.
Thus the issue should be on Send rather than on file reading.
The content of my file is something like this (repeated for about 20 rows more):
+---------------------------------
120001267381 ~ TEXT 0 10/20/18 VARIABLE word text -> numbers: 17,000 x 108.99 | 109.26 x 15,000 /// number = +5.500% some text
+---------------------------------
120001267381 ~ TEXT 0 10/20/18 VARIABLE word text -> numbers: 17,000 x 108.99 | 109.26 x 15,000 /// number = +5.500% some text
+---------------------------------
120001267381 ~ TEXT 0 10/20/18 VARIABLE word text -> numbers: 17,000 x 108.99 | 109.26 x 15,000 /// number = +5.500% some text
+---------------------------------
120001267381 ~ TEXT 0 10/20/18 VARIABLE word text -> numbers: 17,000 x 108.99 | 109.26 x 15,000 /// number = +5.500% some text
+---------------------------------
What can be the cause of this?

Answer 1

Found the answer: due to the fact that + symbols read from my file are sent like pressing the Shift key, the output is amended by the pressing of such a key instead of sending the original symbol present in file.
In order to send the original content of my file without triggering special hotkeys, I have to use SendRaw instead of Send, like in this example:
^+k::
{
Gosub, MySub
}
Return
MySub:
{
Send, +{Enter}
Loop, read, C:\MyFile.txt
{
temp = %A_LoopReadLine%
SendRaw, %temp%
Send, +{Enter}
}
}
Return

Answer 2

Here's an updated version that pastes using CTRL-V instead of Send to "retype" rows of data:
^+k::
{
Gosub, MySub
}
Return
MySub:
{
Send, +{Enter}
Loop, read, C:\MyFile.txt
{
temp = %A_LoopReadLine%
Clipboard = %temp% ; Write to clipboard
Send, ^v+{enter} ; Paste from clipboard
Sleep 10
; Short delay so it doesn't try to paste again before the clipboard has changed
; This check can get a lot more complex, but just increase it if 10 doesn't work
}
}
Return
