The Bug:

The Minecraft Launcher performs automatic conversion to uppercase in various places, depending on the font used. For example, even though the string for the play button is “Play”, it appears as “PLAY” on the play button itself. This conversion is very straightforward in the source language and hence works as intended in English.

However, this case conversion appears to behave inconsistently in other languages, such as Greek. Greek has to follow a set of rules when a word or sentence is fully capitalized and, as a result of this conversion to uppercase, Greek translations appear to have undesirable accents in the fully capitalized text, which go against the language’s rules. This is because the strings on Crowdin appear in their lowercase form and hence are translated as such, but in some cases the Launcher may use them in their uppercase form instead so it performs case conversion automatically.

This issue can be partially dealt with by translators by simply translating the string in its uppercase form so that the Launcher will not convert it incorrectly. However, this would not be possible if the string were to appear in both the uppercase and lowercase form (see “Play” in the next paragraph).

Observed Behavior:

In the attached screenshot of the Launcher main page (screenshot1.png), the string “Play” which is only available in its lowercase form on Crowdin, has been translated to “Παιχνίδι” in Greek and contains an accent. The same string appears in two instances on the Launcher as shown in (1) and (2). In (1), the string appears in its original form, exactly as it was translated on Crowdin. In (2), the string is converted to uppercase by the Launcher. The accent is no longer there, and this behavior is expected in Greek.

In (3), there is the string “Coming Summer 2020”. Just like “Play”, this one is available in its lowercase form on Crowdin, and it has been translated as “Έρχεται Καλοκαίρι του 2022”, which also contains accents. The Launcher again applies an uppercase conversion mapping, but this time the accents are still present, which is not expected in Greek.

As such, it seems there is an inconsistency in the way conversion to uppercase characters takes place in the Launcher. In (2), this was done properly, but in (3) it was not.

Expected Behavior:

Neither (2) nor (3) should have accents in their uppercase form:

• →  “Παιχνίδι” > “ΠΑΙΧΝΙΔΙ”
• →  “Έρχεται Καλοκαίρι του 2022” > “ΕΡΧΕΤΑΙ ΚΑΛΟΚΑΙΡΙ ΤΟΥ 2022”
