I can see the symbol for angstrom () correctly in Word,IE,and other applications installed on my computer. So there is not anything wrong with the font files. However, I can not input it in Origin text labels. Or any other symbol with ASCII code larger than 132. why? When I input with either symbol map or copy & paste with the help of Characater map, it just beeps without anything added into the text labels. What's wrong with my Origin?
The angstrom character () is located in the extended area of the ASCII table, and in the Japanese operating system (as I assume), "half-width" Katakana characters are arranged in that area for Japanese code page.
If you want to force Origin to use Western code page, you can put @FC=0 in the script window before entering the character. (Then you cannot use half-width Katakana with a Western font). (This should work at least in Origin 7.5, but I'm not sure whether it does, or not in earlier version.)
