Hi, @coises and all,
Yes, @coises, you were right about it. So, in short, against my Total_Chars.txt file :
The regex \p{Mn} does return 2,059 occurrences, whatever the case option is cheked or not
The regexes [\x{0300}-\x{036F}], (?=[\x{0300}-\x{036F}])\p{Mn} and (?=\p{Mn})[\x{0300}-\x{036F}] return 112 occurrences, when the Match case option is checked
The regexes [\x{0300}-\x{036F}], (?=[\x{0300}-\x{036F}])\p{Mn} and (?=\p{Mn})[\x{0300}-\x{036F}] return 111 occurrences, when the Match case option is not checked
You said :
All the characters, in range [\x{0300}-\x{036F}], case fold to themselves, except for the single character U+0345 which case folds to U+03B9
This certainly explains why Columns++, taking account of the folding cases, in this specific range [\x{0300}-\x{036F}] ONLY, just finds 111 occurrences, when the Match case option is not checked !
I would say that any range, with defined characters ( so, not using your restriction to be automatically sensitive ) :
When the Match case option is checked :
Finds the
exact number of Unicode chars between the
two boundaries of that range. For example, the regex
[A-z] returns
58 occurrences and is
identical to the range
[ABCDEFGHIJKLMNOPQRSTUVWXYZ\[\\\]\^_\x60abcdefghijklmnopqrstuvwxyz] with, either,
N++ and
Columns++
When the Match case option is not checked :
Finds ONLY the characters of that range which case fold to a character of this range. Thus, the regexes [A-z] and [ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz] return 52 occurrences with N++ ( 26 + 26 )
Finds ALL the Unicode characters which case fold to a character of that range. Thus, the regex [A-z] return 54 occurrences with Columns++ : 52 + 2 chars, whose case folding ( s and k ) belongs to the specific range [A-z]
And note that the regex [ABCDEFGHIJKLMNOPQRSTUVWXYZ\[\\\]\^_\x60abcdefghijklmnopqrstuvwxyzſK] and even [ABCDEFGHIJKLMNOPQRSTUVWXYZ\[\\\]\^_\x60abcdefghijklmnopqrstuvwxyz] return 60 occurrences ( 58 + 2 ), with Columns++, when the Match case option is not checked !
