Byte	This is a synonymous of the Pos method.
Chr	Returns a character from its Unicode value. It is UTF-8 encoded.
Code	Returns the Unicode value of a character inside an UTF-8 string.
Comp	Compares two UTF-8 strings, and returns:
InStr	Returns the position of the first occurrence of Pattern in String.
Index	Returns the index of the character at position Pos in the string.
IsValid	Return TRUE if String is a valid UTF-8 string.
LCase	Returns an UTF-8 string converted to lower case.
Left	Returns the Length first characters of an UTF-8 string.
Len	Returns the length of an UTF-8 string in characters.
Lower	This is a synonymous for the String.LCase method.
Mid	Returns a substring containing the Length characters from the position Start.
Pos	Returns the position of the character of index Index in the string.
RInStr	Returns the position of the last occurrence of Pattern in String.
Right	Returns the Length last characters of an UTF-8 string.
UCase	Returns an UTF-8 string converted to upper case.
UCaseFirst	Return the string with its first letter converted to upper case.
Upper	This is a synonymous for the String.UCase method.

Be careful because standard Gambas string routines only deal with ASCII strings.

To use a non-UTF8 string you must first convert it with Conv$.

Example

DIM hFile AS Stream DIM sOneNonUTF8Line AS String DIM sUTF8Line as String ' Print a WINDOWS-1253 text file to standard output hFile = OPEN "/home/ilias/sometextingreekWINDOWS-1253.txt" FOR INPUT WHILE NOT Eof(hFile) LINE INPUT #hFile, sOneNonUTF8Line sUTF8Line = Conv$(sOneNonUTF8Line, "WINDOWS-1253", "UTF-8") PRINT sUTF8Line 'alternatively 'LINE INPUT #hFile, sOneNonUTF8Line 'PRINT Conv$(sOneNonUTF8Line, "WINDOWS-1253", "UTF-8") WEND FINALLY ' Always executed, even if an error is raised CLOSE #hFile CATCH ' Executed only if there is an error PRINT "Cannot print or read or convert lines from file "; "/home/ilias/sometextingreekWINDOWS-1253.txt"
