Script

class Script

The PangoScript enumeration identifies different writing systems.

The values correspond to the names as defined in the Unicode standard. See Unicode Standard Annex 24: Script names

Note that this enumeration is deprecated and will not be updated to include values in newer versions of the Unicode standard. Applications should use the UnicodeScript enumeration instead, whose values are interchangeable with PangoScript.

Methods

class Script

for_unichar(ch: str) → Script

Looks up the script for a particular character.

The script of a character is defined by Unicode Standard Annex 24: Script names.

No check is made for ch being a valid Unicode character; if you pass in invalid character, the result is undefined.

Note that while the return type of this function is declared as PangoScript, as of Pango 1.18, this function simply returns the return value of unichar_get_script. Callers must be prepared to handle unknown values.

Added in version 1.4.

Deprecated since version 1.44.: Use unichar_get_script()

Parameters:: ch – a Unicode character

get_sample_language(script: Script) → Language | None

Finds a language tag that is reasonably representative of script.

The language will usually be the most widely spoken or used language written in that script: for instance, the sample language for CYRILLIC is ru (Russian), the sample language for ARABIC is ar.

For some scripts, no sample language will be returned because there is no language that is sufficiently representative. The best example of this is HAN, where various different variants of written Chinese, Japanese, and Korean all use significantly different sets of Han characters and forms of shared characters. No sample language can be provided for many historical scripts as well.

As of 1.18, this function checks the environment variables PANGO_LANGUAGE and LANGUAGE (checked in that order) first. If one of them is set, it is parsed as a list of language tags separated by colons or other separators. This function will return the first language in the parsed list that Pango believes may use script for writing. This last predicate is tested using includes_script. This can be used to control Pango’s font selection for non-primary languages. For example, a PANGO_LANGUAGE enviroment variable set to “en:fa” makes Pango choose fonts suitable for Persian (fa) instead of Arabic (ar) when a segment of Arabic text is found in an otherwise non-Arabic text. The same trick can be used to choose a default language for HAN when setting context language is not feasible.

Added in version 1.4.
