Calc should understand unicode mathematical operators
Last modified: 2013-08-07 15:12:27 UTC
calc should understand unicode mathematical operators in addition to traditional ASCII approximations : - U+2212 MINUS SIGN − - U+00D7 MULTIPLICATION SIGN × - U+2215 DIVISION SLASH ∕ - U+00F7 DIVISION SIGN ÷ ... Now the locale on most FLOSS systems is unicode-based only app limitations block the redefinition on the numeric keypad with actual math symbols gnumeric already supports minus As screen technology improves users have started noticing the differences in rendering between minus and hyphen (unicode.org asks for the glyph to be drawn with different sizes: - vs − wich means a mixed plus/hyphen list looks bad +-+-+-+-+ instead of +−+−+−+−+−+−+−+ with a real minus
I believe the idea is to have Calc understand and consider equivalent the traditional operators and their new Unicode counterparts. Why this is useful? 1. There are new keyboard maps that cover more parts of the Unicode standard. 2. A user may paste a table from a Web page that uses the more elegant new Unicode characters. I suppose at this stage Calc should show the traditional operators, is that correct?
IMHO the simplest thing would be for calc to understand both and dispaly whatever operator the user typed I think gnumeric displays hyphen in place of minux in addition to understanding minus and hyphen
Gnumeric actually transforms Unicode minus to legacy hyphen-minus. So the hyphen-minus is saved and when displayed, it is Unicode minus.
Not a defect but an enhancement request. So reflagged and re-assigned to requirements.
As evidenced there : https://bugs.freedesktop.org/show_bug.cgi?id=8240 Xorg/XFree86 keyboard maps are being converter to unicode versions Assuming the keyboard outputs american ascii symbols is therefore dangerous The safest course for the OO.o UI would be to learn all the different unicode variants of any given symbol it takes as input
