I was playing around with inputting regex patterns in https://regex101.com/
Beginning with the most simple of examples (see screenshot image below) I don’t understand the explanation for my pattern '.' (all characters except line terminators) I am assuming that the index values provided are referencing number base terminology. That is 39 base 10, 27 base 16 & 47 base 8?
If I am correct then what is this indexing telling me?
I understand start indexes as used in the following: MathWorks regexp But this particular example, I have posted here, has regex101 referencing the single quote itself.
Perhaps my question is a little esoteric but I would appreciate any suggestions.
>Solution :
The quote char ', the ASCII code representation’s are either:
39 is decimal,
27 is hex,
47 is octal
