How to stop symbols from activating autocorrect?

[nathananaru]

hellooo

I have added custom words to auto correct which i use a lot however certain codes are separated by the "_" symbol.

e.g. "y_sq" would auto correct to "Yellow Square"

but whenever i try to type it will autocorrect when i press the "_" button.

e.g. before I can finish typing "y_sw" it becomes "Yellow_sq"



The only solution I have now is using Ctrl+z each time it autocorrects, but this becomes an issue as I have some codes seperated by multiple underscores

e.g. "y_sq_bg_12" = "Big 12cm Yellow Square"

I do hope this can be fixed
