This project can convert any positive base 10 integer into any base between 2 to 318. It has an extremely short and compact code, compared to others that I've seen. It supports the following characters: 0123456789abcdefghijklmnopqrstuvwxyzᗩᖲᙅᖱᗴℱᘐᖺᓰᒎḰᒪᙢﬡᗝᕈᕋᖇᔕ☂⋒ᐯᙡჯᎩᔓa̶b̶c̶d̶e̶f̶g̶h̶i̶j̶k̶l̶m̶n̶o̶p̶q̶r̶s̶t̶u̶v̶w̶x̶y̶z̶ⓐⓑⓒⓓⓔⓕⓖⓗⓘⓙⓚⓛⓜⓝⓞⓟⓠⓡⓢⓣⓤⓥⓦⓧⓨⓩ☺☻♥♦♣♠•◘○◙♂♀♪♫☼►◄↕‼¶§▬↨↑↓→←∟↔▲▼!"#$%&'()*+,-./ [\]^_`{|}~⌂üéâäàåçêëèïîìæôöòûùÿ¢£¥₧ƒáíóúñªº¿⌐¬ ½¼¡«»░▒▓│┤╡╢╖╕╣║╗╝╜╛┐└┴┬├─┼╞╟╚╔╩╦╠═╬╧╨╤╥╙╘╒╓╫╪┘┌█▄▌▐▀αßΓπΣσµτΦΘΩδ∞φε∩≡±≥≤⌠⌡÷≈°∙•√ⁿ²■
78 out of 318 characters are from @World_Languages https://scratch.mit.edu/projects/79374426/. Working on converting the number back. Try typing a super large number and convert to base 318! :D P.S. Not too too large though, because Scratch can't calculate it, and the output will be messed up.
