You are flaunting your ignorance. Values above 127 (decimal) have a variety of symbols attached. The manual for my HP printer has several pages of built-in symbols, with 25 different character sets. What shows up as a Greek omega in one, is a German U-umlaut in another, just from an instantaneous glance. Use anything from 127 upward, and you cannot count on any one else seeing what you do.
Then there are the Wingdings and Zapf Dingbat fonts, even in the lower numbers. And Ventura Math, Pi Math, Math-8, PS Math fonts playing in the lower range, too, all from the RTFM part of the HP printer manual.
