## Conversions
|
|
|
|
|From | To | Example |
|

|
%fnametoftext%
|
|
%fstringtofname%
|
|
%fstringtoftext%

|
%ftexttofstring%

|
|
|
|
[VAR:FNameToFString]
|
|
|FName | FString | `TestHUDString = TestHUDName.ToString();` |
|
|
[/VAR]
|
|
|
|
[VAR:FNameToFText]
|
|
|FName | FText | `TestHUDText = FText::FromName(TestHUDName);` [REGION:warning] FName -> FText is valid in some cases, but be aware that the FNames's content will not benefit from the FText's "auto localization". [/REGION] |
|
|
[/VAR]
|
|
|
|
[VAR:FStringToFName]
|
|
|FString | FName | `TestHUDName = FName(*TestHUDString);` [REGION:warning] FString -> FName is dangerous as the conversion is lossy as FName's are case insensitive. [/REGION]|
|
|
[/VAR]
|
|
|
|
[VAR:FStringToFText]
|
|
|FString | FText | `TestHUDText = FText::FromString(TestHUDString);` [REGION:warning] FString -> FText is valid in some cases, but be aware that the FString's content will not benefit from the FText's "auto localization". [/REGION] |
|
|
[/VAR]
|
|
|
|
|
|
[VAR:FTextToFString]
|
|
|FText | FString| `TestHUDString = TestHUDText.ToString();` [REGION:warning] FText -> FString is dangerous as it is a potentially lossy conversion for some languages. [/REGION]|
|
|
[/VAR]
|
|
|
|
[VAR:FTextToFName]
|
|
|FText | FName | There is no direct conversion from FText to FName. Instead, convert to FString and then to FName. [REGION:warning] FText -> FString -> FName is dangerous as the conversion is lossy as FName's are case insensitive. [/REGION]|
|
|
[/VAR]

## Encoding
|
|
|
|
In general, you should be using the **TEXT()** macro when setting string variable literals. If you do not specify the TEXT() macro, your literal will be encoded using ANSI, which is highly limited in what
|
|
characters it supports. Any ANSI literals being passed into FString need to undergo a conversion to TCHAR (native Unicode encoding), so it is more efficient to use TEXT().
|
|
|
|
For more about encoding, see the [](Programming\UnrealArchitecture\StringHandling\CharacterEncoding) documentation.
