Tweaking Fonts and Layout in Canvas HTML Editor
The Helvetica Neue font in the Canvas interface does not support all technical symbols (e.g. some phonetic symbols or lesser known characters from Old English).
Note: Helvetica Neus does support characters for major Western languages like Spanish, French, German and Italian and also Russian and basic Greek.
Increase Font Size
This CSS technique can also be useful to resize some non-Western scripts to make the font be larger. Note that Canvas supports font sizes in ems. A font size of 1.5em may work for many scripts.
Switch Text Direction
Canvas supports the use of the
dir="rtl" for right to left text layout for languages like Arabic and Hebrew. See the RTL page for details.
Beyond the HTML Editor
Layout options are more limited outside the Rich Content/HTML Editor in location such as item titles. If you need to use non-English characters in Canvas, be aware that some display quirks may be seen.
