ASCII char. in an objet string

[admin]

You can use any UTF-8 characters but it is advised to use 250-byte string object because other type are too short.
Spaces are collapsed by your browser, it's how HTML works. You can use no-break space character to put several spaces together:

Code:

nbsp = string.char(0xC2, 0xA0)
grp.update('32/1/1', '123' .. nbsp .. nbsp .. 'Ω')
