Remarks
How to use a specific character set?
To use a specific character set, you must:
- Install the files corresponding to the requested character sets in the regional settings of Windows (control panel).
- Use ChangeCharset in your program.
Changing the character set used by the fonts
ChangeCharset modifies the character set used by all fonts. The fonts that use the requested character set must be installed on the current computer.
ChangeCharset takes effect immediately. We advise you to close and re-open all the windows or pages.
Changing the character set used by the operations performed on the character strings
ChangeCharset modifies the character set used by the operations performed on the character strings. This new character set will be taken into account:
- when comparing two strings according to the lexicographical order (StringCompare associated with the ccLexicographicOrder constant). This comparison does not take the "double letters" into account (CH in Spanish or LJ in Croatian for example).
- in the HFSQL indexes (Classic mode or Client/Server mode) once the indexes have been built or rebuilt (HCreation, HCreationIfNotFound or HIndex associated with the hChangeCharset constant). The sort order in the indexes does not take the "double letters" into account (CH in Spanish or LJ in Croatian for example).
ChangeCharset takes effect immediately. We advise you to close and re-open all the windows or pages.
Changing the character set control by control
You also have the ability to modify the character set used control by control with
..FontCharset.
Using the charsetUTF8 constant
The charsetUTF8 constant is used to manage the countries with two character sets (Hong Kong) and the countries with no character set defined in Windows.
In this mode, if a Latin character set is used, the accented characters are not coded on one byte but on several bytes. A character can be coded on 4 bytes.
This operating mode triggers specific effects when managing the character strings.
For example,
Length does no longer return the number of characters but the number of bytes corresponding to the string. We recommend that you use
UnicodeToAnsi before performing specific operations on the character strings.
