Function Documentation

◆ AppendStringInPlace()

void AppendStringInPlace	(	std::string &	result,
		StringID	string
	)

Resolve the given StringID and append in place into an existing std::string with all the associated DParam lookups and formatting.

Parameters

result	The std::string to place the translated string.
string	The unique identifier of the translatable string.

◆ CheckForMissingGlyphs()

void CheckForMissingGlyphs	(	bool	base_font,
		MissingGlyphSearcher *	searcher
	)

Check whether the currently loaded language pack uses characters that the currently loaded font does not support.

If this is the case an error message will be shown in English. The error message will not be localized because that would mean it might use characters that are not in the font, which is the whole reason this check has been added.

Parameters

base_font	Whether to look at the base font as well.
searcher	The methods to use to search for strings to check. If nullptr the loaded language pack searcher is used.
