@egreg Does Page 68 in the "Comprehensive List of LaTeX Symbols" mean "Table 134: MnSymbol Triangle Relations", I didn't find Indicator function symbol in that page, actually I didn't find anything about Indicator function through whole manual. – JJJohn Nov 12 '19 at 08:47

@JJJohn It's now table 307, page 119 in the much expanded list. See the “blackboard bold fonts”. – egreg Nov 12 '19 at 08:50
